Saltwater Fish
Royal Gramma.
A pocket showpiece — vivid purple fading to gold across the body. Hardy, reef-safe, and beginner-friendly, though it'll defend a favorite cave. A splash of color for any 30-gallon-plus reef with rockwork to claim.

Live animals are sold in store only — we do not ship fish, coral, or invertebrates. Every animal is acclimated and health-checked in-house before it reaches the sales floor. This is a species we carry — it's most likely in the tanks around delivery days, but live stock changes daily. Please call (814) 456-9445 to confirm availability before you drive in.

Good tank mates
The royal gramma is a small, hardy, mostly peaceful reef fish that suits community tanks with clownfish, firefish, gobies, tangs, and similar calm species. It is territorial around its chosen cave or overhang and will flare at intruders, so give it rockwork to claim and avoid housing it with the lookalike royal dottyback or a second gramma in a small tank, as well as large predators that could eat it.
Good to know
Royal grammas often swim oriented to the nearest surface, so they can be seen hanging upside down under ledges and in caves as if the rock were the floor.

Ultra Black Ice
Both species are genuinely peaceful and occupy non-overlapping niches — the clownfish bonds to an anemone or a fixed corner while the gramma claims a rockwork cave, so there is no territorial contest. They share identical temperature (72–78°F), salinity, and tank-size minimums, and multiple keeper accounts confirm stable coexistence even in tanks as small as 30 gallons when introduced together or clownfish-first.
Green Chromis
Chromis viridis cruise the open water column well above the gramma's rockwork, producing zero territorial overlap. They are genuinely non-aggressive for a damselfish and are universally listed as reef-safe without any coral-nipping caveats. Keeping them in a small school of 6+ is recommended for their own wellbeing but does not introduce any new compatibility risk with the gramma.
- N
Neon Goby
At under 2 inches the Neon Goby presents zero predation risk from a 3-inch gramma, and its role as a cleaner fish grants it de facto behavioral immunity — even territorial hosts tolerate cleaners on their rockwork. It operates as a cleaning station on exposed reef surfaces rather than retreating into defended caves, so there is no shelter competition with the gramma.
