Species Overview
Clownfish
The ocellaris clownfish is a protandrous sequential hermaphrodite that lives in a mutualistic relationship with sea anemones. Its mucus coating protects it from anemone stings. All individuals are born male and the dominant fish transitions to female.
Oscar
The oscar is a large, intelligent cichlid native to the Amazon basin. Known for its dog-like personality, it can recognize its owner and may beg for food. Oscars rearrange their tank decor and require spacious aquariums with robust filtration.
