Black Cap Basslet (Gramma melacara)
The Black Cap Basslet is a stunning addition to a saltwater aquarium, known for its deep purple to magenta body and distinctive black marking that covers the top of its head. Native to deeper Caribbean reef environments, this species is naturally found around steep reef walls, caves, and rocky ledges.
What makes this fish interesting is its behaviour. The Black Cap Basslet enjoys staying close to rockwork, often positioning itself underneath ledges or inside caves. It may even swim upside down beneath rock overhangs, which is completely normal for this species. While it can be shy when first introduced, it often becomes more confident once it has established a comfortable hiding spot.
Care & Temperament
The Black Cap Basslet is generally peaceful toward most community fish but can become territorial, especially when defending its favourite cave. It does best in an established aquarium with plenty of live rock and shaded areas.
-
Provide plenty of caves, crevices, and overhangs.
-
Prefers areas with moderate lighting and sheltered spaces.
-
Can be territorial toward other basslets and similar-looking fish.
-
Best kept individually in most home aquariums.
-
A tight-fitting lid is strongly recommended, as this species is known to jump.
-
May spend much of its time near its chosen hiding spot, especially when newly introduced.
Diet
The Black Cap Basslet is a carnivore that feeds on small crustaceans and other meaty foods. It generally adapts well to aquarium feeding and should be offered a varied diet to maintain good health and colour.
Recommended foods include:
-
Mysis shrimp
-
Enriched brine shrimp
-
Chopped shrimp and other marine seafood
-
Frozen marine carnivore preparations
-
Quality marine pellets and flakes
Tankmates & Compatibility
The Black Cap Basslet can make a great community reef fish when housed with suitable tankmates. It generally gets along with peaceful fish but may defend its territory against other basslets.
Good tankmates: Clownfish, cardinalfish, gobies, blennies, peaceful wrasses, anthias, and appropriately sized tangs.
Use caution with: Other basslets, Royal Grammas, dottybacks, and similarly territorial cave-dwelling fish. Avoid aggressive fish that may intimidate it or prevent it from feeding.
Reef Safe
Yes – Reef Safe.
The Black Cap Basslet is considered reef safe and will generally leave corals, anemones, and most ornamental invertebrates alone. However, it naturally feeds on small crustaceans, so tiny shrimp and microfauna such as copepods and amphipods may be eaten.

Health & Acclimation Notes
The Black Cap Basslet may be shy when first introduced and can spend several days hiding among the rockwork while adjusting to its new surroundings. Providing shaded areas and plenty of hiding spots will help it settle in.
We recommend a slow, careful acclimation process and keeping the

LIGHT
LOW: Place coral at the bottom of the tank. Depending on the type, coral may need to be placed off sand and therefore mounted on a ceramic disc of piece of rock.
MEDIUM: Place coral at mid-range of the tank. Best placed/glued on top of a rock scape at mid-range height.Â
HIGH: Place coral from mid range to just below water level. SPS coral are shallow growing so they require and are able to tolerate intense light.
FLOW
LOW: Most soft coral do well with a small, gentle pulse. There are certain corals that can even be placed in areas of indirect flow, meaning places aside a rock structure or set into a entrance to a cave style space.
MEDIUM: Many LPS types of coral prefer medium pulse current. Most Euphyllia or corals that have more tissue structure connected to their skeleton, don’t like to be in a high flow area like the direct flow of the wave pump.
HIGH: Similar to high light, SPS enjoy being in some heavy current. Most LPS and SPS that branch encrust or plate prefer high flow that simulates the top water waves.
SKILL
ENTRY: While some may say beginner level, "Entry" is a good term to be used when starting out in the world of corals and marine life. Prior to adding livestock, you want to ensure that your reef has the proper parameters including zero levels of ammonia and nitrite. Seeing traces of nitrate in your waters is a good sign - just keep them at a lower level of 2ppm to 10ppm. Maintaining correct temperature and salinity are a huge factor to stable parameters. Starting to monitor your PH, alkalinity, calcium and magnesium is a great habit to get into to keep a successful reef.
While some soft coral don’t require too much light, having a proper reef light that puts out the proper pars is very important. You'll also want to have a good amount of flow and protected rock areas, as placing corals in their happy spot is ideal for success.
