Scientific Name:

Other Common Names for the Blackcap Basslet:
Blackcap Gramma


The Blackcap Basslet is found in the Western Pacific Ocean, from Java to Fiji, and from the Ryukyu Islands to the Great Barrier Reef.  This member of the Grammatidae family has brilliant coloring. Their bodies vary in color from bright magenta to purple. They are named for the jet-black, diagonal cap running from their lower lip to their dorsal fin. They are considered hardy and disease-resistant. A Blackcap Basslet can reach up to 4 inches in length and requires an aquarium of at least 30 gallons with plenty of room to swim.


Blackcap Basslets are carnivorous. Their diet should be varied and consist of things like frozen brine shrimp, Mysis shrimp, copepods, pellets, flake food, fish flesh, and prepared or frozen offerings.


As stated earlier, a Blackcap Basslet can reach up to 4 inches and requires an aquarium of at least 30 gallons. A Blackcap Basslet is generally happy as long as it has a cave to call home and is in an environment with good water quality. They may go for a look around or to hunt food occasionally, but these particular fish will usually hide in their cave or hover above it. Although the Blackcap Basslet is generally considered peaceful, it may act aggressively toward other Blackcap Basslets, as well as other basslets. It isn’t recommended to keep multiple basslets in one tank. Aggression from this basslet is usually only territorial and is limited to the area of its chosen cave or crevice. If you intend to keep fish - especially a basslet, a netted lid is recommended.
