Although captive-bred fish are often slightly more expensive than wild fish, this can often pay off in the long run. For instance, buying a captive-bred fish means that the fish that would be brought in from the wild to be kept as pets are left in the wild. Because divers bring in fish regularly, the amount of fish in the wild regularly goes down faster than it would naturally. This can cause many species of fish to go extinct when they would have survived if we had left them in the wild and bought captive-bred fish.

Types of wild caught fish and methods of capture

It is mainly saltwater fish that are in danger, as many commercial fish farms breed captive freshwater fish. The fish

are not the only ones in danger, many corals and invert species are also being caught or possibly even destroyed. One of the more popular practices to catch wild fish is called cyanide fishing, and it uses cyanide to suffocate the fish until they pass out. Cyanide can also have harmful effects on the habitat, such as bleaching the coral or even causing death to corals, depending on the amount of cyanide used and the exposure time of the coral to the cyanide. The long-term

effects of the cyanide on the fish that survive this method are unknown.

Advantages of captive-bred fish

Additionally, captive-bred fish have spent their whole lives in an aquarium and are much more accustomed to living in a glass container and are much easier to feed than their wild counterparts. They are also much less aggressive than fish in the wild. Species that are caught in the wild have to go through quite an ordeal to get to the local pet store, which cause many of them to die from stress. Captive-bred fish have a much higher rate of survival since they only have to travel from the local pet store to your aquarium. Wild-caught fish may also have potentially deadly diseases that come from parasites and pathogens that are not found in an aquarium. Captive-bred fish are much more likely to be healthy and disease free as long as they are kept in the proper conditions and are not placed in an aquarium with a diseased fish that was caught in the wild.

In conclusion

Captive-bred fish means that once-wild fish were caught, bred, and then raised under the care of experts in special facilities over generations, although some species can possibly be bred in your aquarium. To see how you can help the spread of captive-bred fish, please contact your local aquarium.

Attention All Fish Hobbyists

It is painful for me to watch this site sit and stagnate. It’s a blog I started a long time ago as a demonstration of how to set up a WordPress Blog on another site of mine. An old love of mine, back when I had an 80 gallon saltwater tank and a 15 gallon freshwater tank.

The sad reality is that I haven’t been able to keep fish for a long time and it looks like I won’t be able to do so anytime soon.

So I’m asking for help, help to keep quality information posted here, to keep the site fresh.

If you keep saltwater or freshwater fish, whether you have a pond or aquarium, I would like to put your knowledge, your stories, here.

Use the contact form to tell me about yourself and what you know. I’d love to post it here as a guest author. If you don’t want to write, but have information, then we can either record it or I can write it for you. I want good information here. Real information, real stories, from real people.

Saltwater Angelfish Quick Care Facts:

Environment: Varies by species
pH: Varies by species
KH: Varies by species
Diet: Omnivore
Breeding: Varies by species

Saltwater angelfish are a colourful species, popular with many aquarium owners. There are several species of marine angelfish, with most species generally reaching lengths of eight to 12 inches.

General Saltwater Angelfish environment

One important aspect of caring for saltwater angelfish is to make sure that the tank intended for them has been in use for at least three months before they are introduced. This ensures that the nitrogen cycle in their new home has been fully established. Ammonia and nitrite levels need to be checked regularly. In general terms, these fish prefer reef tank environments. The size of the tank can vary with the specific species of angelfish you have chosen. Smaller species may require a tank size of around 50 gallons.

Feeding your Saltwater Angelfish

Angelfish need a varied diet in order to thrive. While live foods such as brine shrimp often go down well, frozen scallops or krill will also generally work, too. Commercial foods such as flakes and pellets may also be suitable, but it is wise to check the requirements of your specific species. One crucial thing to remember is that angelfish need around 20 percent of their diet to be vegetable matter such as lettuce. A varied diet helps them stay healthy.

Breeding your Angelfish

Setting up the right tank environment is vital if you want your angelfish to breed. They need to feel comfortable and secure. Angelfish are pelagic breeders in the wild, meaning that they release their eggs into the ocean and let them drift. The biggest challenge facing captive breeders is keeping the eggs alive. All angelfish are born hermaphrodites, but will change sex as their environment alters. If you want your fish to breed, make sure you have a mixed population of smaller and larger specimens. The larger will become males and the smaller ones female. Maintaining a consistent day/night cycle in your aquarium will help your fish breed. Eggs will usually hatch 20 hours after spawning, and should be removed to a separate aquarium.

Saltwater Angelfish diseases

Angelfish are hardy, but can be prone to lateral line erosion, which can scar them. bacterial and protozoan diseases can be a risk if tank environment quality is not maintained. Edema, or bloat, can often prove fatal. The risk of all diseases falls if you pay careful attention to the quality of the environment in which the fish are living.

Care Guide For Trigger Fish

Clown trigger fishTrigger Fish Quick Care Facts:

Environment: Tropical. Water temperature 72-78 degrees Fahrenheit
pH: 8.1-8.4
KH: 8-12
Diet: Carnivore
Breeding: Egg layers

The trigger fish is a tropical reef fish that is among the hardiest of species. It does well and adapts quickly to aquarium life.

Environment for the trigger fish:

This fish can live successfully in a variety of tanks. However, tall or narrow tanks should not be used. An adequately sized aquarium will depend on the species of trigger fish that is going to inhabit it. It is also important to keep in mind the other tank mates that may be present. A larger, roomier tank will allow for a happier, community setting as certain types of trigger fish may become aggressive, especially in small spaces. Triggers can live with other fish, but room mates should be chosen carefully and owners should follow any stock orders given by the supplier. Odd shaped tanks are also not conducive to a happy life for these tropical reef fish.

Feeding your trigger fish:

Feeding these fish can be super easy. In their natural habitat, triggers will browse among the reef and coral for snails, crabs and other small fish. In captivity they will accept a vast array of fish food, whether it is fresh, frozen or previously prepared. In fact, trigger keepers can even shop at the local seafood counter at the grocery store. Bite size pieces of fresh fish, squid, crab and more can be hand fed to the fish. Supplementing periodically with vitamins is key to ensuring that the trigger maintains a healthy diet.

Trigger fish breeding

While breeding is not an extremely common practice among captive trigger fish, some species have been known to reproduce in very large tanks. It is possible but not guaranteed. Females will create a nest in the sand and lay eggs. These eggs are not free floating so any shaped aquarium can successfully protect and promote the birth of new fish.

Diseases of trigger fish

The good news is that this type of tropical reef fish is by far one of the most hardy species. These aquatic animals are extremely resistant to disease. However, they can occasionally be affected by saltwater ick. But with just a bit of extra care and attention, this can be cleared up quite successfully with no detrimental effects.

Caring For Your False Clownfish

False Clownfish Quick Care Facts:

Environment: Tropical 75 – 81°F (24 — 27°C)
pH: 8 to 8.4
KH: 8.0-11.0
Diet: Omnivorous
Breeding: Egg layers

The common clownfish, otherwise known as the false clownfish, the false percula clownfish,  anemonefish, and the ocellaris clownfish, is a very popular breed of saltwater fish. They are beloved for their distinctive colors and vivacious nature.

Aquarium Conditions

In order to feature an enticing environment for your clownfish, it is important to equip the aquarium with a wide variety of caves and corners for the fish to explore. They enjoy the comfort of being able to hide when they feel threatened. This species of fish also works well with reef aquariums, though general rock arrangements are recommended for beginners.

Feeding Recommendations

This species is recommended for new fish owners because they are very easy to feed. The false clownfish is omnivorous and can easily subsist on a wide variety of different foods, including most types of marine flakes. In order to promote the fish’s health, it is recommended to feed it a diet of algae and vegetable based matter along with protein rich food. Keeping algae in the tank can allow them to graze between meals.

Breeding Information

Unlike most saltwater fish, common clownfish are much easier to breed. Initially, all clownfish that are born are male. When paired with other fish, the larger and more dominant fish becomes the female. After matings, eggs are typically laid on a steady and flat surface, like a rock. When the fry hatch, they are much more sensitive to feeding needs than adult clownfish. They should be fed regularly every two to three hours but only very small amounts of food in order to prepare their bodies. They can usually be seperated from their parents after five to six weeks.

Possible Diseases

Much like any other type of fish, keeping the aquarium clean and carefully maintained can cut down on the risk of a lot of diseases. Clownfish are particularly susceptible to several different parasitic infections and fin rot. Symptoms are usually readily apparent and infected clownfish must be quarantined immediately in order to ensure that infections do not spread to other fish.

The Lionfish Care Guide

LionfishLionfish Quick Care Facts:

Environment: Tropical 72-82°F (22-28°C)
pH: 8.1 to 8.4
KH: 1.020 – 1.025
Diet: Carnivorous
Breeding: Egg layers

Lionfish are some of the most impressive aquarium fish around, growing up to 15 inches in length. They also carry an element of danger, as many of their spines are poisonous.

The Lionfish Environment

Large tanks are required for this tropical fish. They need plenty of space and are likely to eat other, smaller fish, even of the same species. The tanks should be at least 30 gallons, but much larger if you have a larger species. The dwarf fish will be fine in 30 gallons.

While lighting can be standard, lions do appreciate caves and lots of overhangs in the tank. They like to “perch” sometimes and will frequently hang out with their heads in crevices. Give them a nice substrate bottom to enjoy, as well.

The tank must be covered, as lions will jump out. Also, you should be aware that they produce a lot of waste, so require a heavy duty filtration system.

Feeding Your Lionfish

These are hunting fish and they prefer to feed at night. Adult fish only require feeding two or three times a week, while babies will need more regular food. You can give them small fish, shrimp and small pieces of frozen tuna or other fish. Only feed until you see a little bulge in the lion’s belly.

Breeding Lionfish

In the wild, these fish only group together when they are about to spawn. In both tank and sea, the males will become very aggressive and turn dark in color. The females become a lighter color.

The mating dance will occur if you leave the fish alone. The female will lay tubes of eggs which will hatch out into larvae in around 36 hours if they are fertilized by a male.

Common Lionfish Diseases

These fish are not likely to get sick, but they can be prone to bloat if they are fed large pieces of food. The food can putrefy in their gut, causing a buildup of gases.

The other disease that may find its way into your tank is Saltwater Fish Disease.

How I Got Started Keeping A Marine Tank

Boy was that some time ago.  A guy I was working with, whose name is Tim  was (and still is as far as I know) really into the hobby.  We were talking about it off and on and I was getting more and more interested in it.

For those of you who read my previous article on how I got into keeping fish in the first place, you know that I had already come into knowing what I was doing the hard way for keeping a tropical freshwater tank.

Now this other guy at work named Scott had a 75 gallon tank from when he had a marine tank and it was sitting there doing nothing.  Having gone through (or was going through, I forget) a divorce, he sold it to me cheap.  I got it, the stand, and accessories for under $100 dollars.  It was the deal of a lifetime and I snatched it up.

I still made mistakes, I still didn’t know a whole lot.  It took forever before I got a protein skimmer. Over time I had a bare bottom tank, then a sand bottomed tank and finally a plenum.  At one point I had a bright blue anemone that was large enough to fill a 10 gallon aquarium all by it’s little lonesome.

Tim told me about a magazine and so I started buying it and reading up on it.  At this point my interest was virtually unstoppable.  I read almost every article in that magazine every time I bought it, I even had a subscription to it at one point.

Over a few years I probably invested $1000 – $2000 dollars into that tank.  $30 here or $40 there before I finally had to give up the hobby.  After I lost my tank (I’ll save that for another post)  I kept a 10 gallon tank (which did very very well) and a small 2 gallon tank that came with a biowheel.

Now I can’t have one at all, sigh.  Anybody interested in posting some pictures of their tanks here?  Seriously, let me know.

Maybe next time I’ll tell you how I lost my 75 gallon tank.  I still cringe.
