Ok so I posted on here about a week and a half ago. I got a dartfish from my LFS and he went into.hidding immediately. Alot of people said they will hide most of the time. But like I said we are going in 2 weeks and I haven't seen him once. Not at feeding time anything. I moved two Rick structures today some people said not to I might crush him so I did it carefully and nothing. There is a few more rocks I have to still move around unless when I pulled the rocks out he was still inside of it somewhere. But i haven't had fish jerky on my floor ever since i got him and my ammonia nitrite and nitrates never jumped indicating a decaying fish. Any thoughts or tips?
