This species is an ideal choice for the beginner saltwater aquarium due to its hardiness and peaceful nature. To ensure a healthy environment, it should be housed in a 30 gallon or larger aquarium with live sand as the substrate and an attached populated refugium. Additionally, the Diamond Watchman Goby uses shallow burrows in the substrate as refuge, keeping the substrate well oxygenated. As it is rarely aggressive towards other fish, it can easily be kept with a range of other tankmates. However, it is territorial and will fight with its own kind unless they are a mated pair.

This Diamond Watchman Goby is an active scavenger and prefers to feed off the bottom as it sifts through the sand. It is important to provide a variety of live and frozen foods such as brine shrimp, mysis shrimp, live black worms, and prepared foods for carnivores. It should be fed frequently to ensure its optimal health. Additionally, the substrate should be kept clean and free from contaminates as this species is known to use the substrate to search for food. Regular water changes and maintenance should be performed to ensure the health and well-being of your Diamond Watchman Goby.

Purchase sizes will vary depending on the garment’s style and fabric.
