Species Profiles
Pea Puffer
Carinotetraodon travancoricus
Pea puffers are the smallest freshwater pufferfish in the world, growing to just 1 inch. Despite their tiny size, they have big personalities — they are curious, intelligent, and surprisingly aggressive. They are best kept in species-only tanks and require live or frozen food.

Amphiprion ocellaris
The ocellaris clownfish — star of Finding Nemo — is the most popular saltwater aquarium fish and one of the best choices for beginner reef keepers. Captive-bred specimens are hardy, readily available, and don't require an anemone host (though they will happily adopt one). They are one of the few marine fish that breed regularly in home aquariums.
