Saltwater Aquarium Fish and Freshwater Tropical Fish

Compatibility There are many differing ideas aboutthe compatibility of angelfish with other fish. As a general rule they are compatible with tetras, platies, mollies, loaches, swordtails, plecostomus, danios and gouramis. In addition, the size of the aquarium can determine how well your fish get along. Crowded fish are stressed out fish and by and large are more aggressive.
