Blackcap Basslet

The Blackcap Basslet (Gramma melacara) is a rich purple color with a black head. Looks like they are sporting a black cap. They get to about 4 inches in size (10 cm) and are considered hardy. They acclimate to aquarium life well and may even be mostly captive raised nowadays. They were one of the original species to have been bred in captivity. Provide plenty of cover in the form of live rock and feed them a couple times per day with meaty type marine origin foods or micro pellets.

You can usually buy a Blackcap Basslet for around $40.
