17 days now. The tang seemed to go through a normal adjustment period, where he was timid for a week or so before he’d really actively swim around the tank. He’s fairly small.
Assuming that bullying is the culprit, am I better off with a different Cirrhilabrus species? At very least, I’ve learned that I should’ve used an acclimation box.
Like Tcook said, they are notorious for being wimps. So even if no one was being aggressive in the tank, he might’ve been really hesitant and scared to come out and eat if he thought he had to compete.
In the future keeping him in an acclimation box for a few days and feeding him a lot will help him get some confidence and nutrition (they don’t really eat in transit) that will build his strength. And over feed your tank once you release so that no one feels like they have to compete, because there’s plenty for everyone.
And one last thing, it’s always possible he was unwell before you got him. Just weakness and stress from shipping, being in a store, etc.
