Nerite snails are the best algae-eating snails for freshwater aquariums. They come in beautiful patterns (zebra, tiger, horned, olive) and will not reproduce in freshwater — making them the ideal pest-free algae cleanup crew. A single nerite can keep a 5-gallon tank virtually algae-free.

Oscars are large, intelligent South American cichlids often called 'water dogs' for their interactive personality. They recognize their owners, beg for food, and can be hand-fed. However, they grow fast, produce massive waste, and need at least a 75-gallon tank.
