I added a chalk goby, but had to sump him. The trigger thought it was food. I would need about 3 of them in a 5ft system. Would a tuxedo urchin be good or would it destroy that?
A goby will stay at the bottom sifting through sand. I’m talking about blennys, like a lawnmower blenny (has that name for a reason, it mows through algae) or a starry blenny. Blennys house themselves within the rock structure as opposed to gobies staying at the bottom within the sand. A tuxedo urchin really has no defense against the trigger & will become lunch, it’s the reason I recommend a black long spine, the spines are toxic & long enough to keep the trigger at bay. What makes it difficult to recommend a good CUC is the trigger, otherwise I would say to get emerald crabs, hermit crabs, variety of snails, serpent sea stars, sea squirts, shrimps & a sand dollar. Triggers are like pit bulls, they will gnaw on anything while looking for food & if it’s meaty, they will make a quick snack out of it.
