Rummy nose tetra - I really like these but cannot find them in northern Louisiana. Like many fish when they are stressed their colors disappear. This does not help them "sell" in pet stores if people are not familiar with them! The color comes back though once they feel safe.
There are many kinds of Triggerfish. This is a Clown Triggerfish. They are very feisty and will bite your hand when trying to feed them. If you keep them in an aquarium they will bite tubes and stuff and cause real havoc! They have personality.
