The Citrinis Clown Goby is a beautiful addition to a reef aquarium, however caution should be exercised when adding this fish to an SPS dominated tank. This species feeds on the mucous polyps of Acropora sp. in the wild and is considered reef safe, but it may nip at the polyps or bases of Acropora sp. and other SPS corals. Therefore, it is important to ensure that the SPS dominated aquarium is heavily stocked with mature colonies to prevent any potential damage. Additionally, regular maintenance and monitoring of the aquarium is essential to ensure the health of the fish and the coral.

This majestic fish, the Royal Gramma, is a pleasure to behold. It is a vibrant, deep purple and yellow fish that is found in Caribbean reefs. It requires a 10 gallon or larger aquarium and prefers branched corals, often resting on them for hours at a time. It is an active swimmer, but will also find places to hide in the reef. It will rarely become aggressive towards other fish, but will fight with its own kind in smaller tanks. To ensure its safety, it is best if it is kept with other docile species. When kept under the proper conditions, the Royal Gramma is a beautiful addition to any home aquarium. Keeping the Royal Gramma in a larger tank with compatible fish will ensure a happy and healthy environment.

It is common for clown gobies to spawn in an aquarium. If you are concerned about the possibility of spawning clown gobies in your aquarium, be sure to keep an eye on the aquarium’s SPS corals. They will lay their eggs on the underside of the coral’s branch, which will cause tissue recession in that area of the coral.
