Species Profiles
Cardinal Tetra
Paracheirodon axelrodi
Cardinal tetras look similar to neon tetras but have a red stripe that extends the entire length of their body (vs only the back half in neons). They prefer softer, more acidic water and are slightly more delicate, but their deeper coloration makes them highly sought after.

Amatitlania nigrofasciata
Convict cichlids are tough, prolific Central American cichlids with distinctive black and white vertical stripes — earning them the 'convict' name. They are extremely hardy, breed readily (almost uncontrollably), and are highly aggressive for their size, especially when protecting fry. They are excellent for beginners who want to keep cichlids but should not be mixed with peaceful community fish.
