It is only a good sign if you wanted to breed snails. Snails are pests that can destroy the ecosystem in your aquarium, regardless of the type of aquarium. If you are breeding snails (for whatever reason), use an aquarium devoted to your snail breeding. As others have said about snail infestations, when they die they decay, producing ammonia and other poisons. With fish, this can lead to lowered immune function, disease, and eventually death. If you don't want the snails, you can remove them with medicines sold at your local pet store. ~Wigglerthefish Fish Help Forum

Sorta... Depends on what fish you are talking about.
You can find good quality tropical fish at Petsmart near your surrounding area. They have a good variety of fishes that you can choose from and sale at a reasonable price.

Tropical fish must be mixed with other fish that are well adapted to the same community as the tropical fish are. These would be fish that are non-aggressive, and like basically the same foods, water temperatures, plants and environment.
