Saltwater Fish

I love fish - live ones :) - especially the colorful ones, such as saltwater fish. It's rather amusing, however, that so many will eat each other. A fairy basslet (latin, gramma loreta), for instance, is three inches long and half purple and half yellow. Part of its diet is 'crustacean flesh' - so, snails, crabs, and other like critters are likely to be eaten in an aquarium. Actually, a rule of thumb for these animals is 'if one can fit into the second's mouth, it will probably end up there'. Certain fish, like eels, surgeonfish, and puffers have a tendency to only put up with their own species. Good thing the ocean's so big, mmh?
