The hermits are the only clean up crew I have. I wasn't sure what else to get.
The aquarium has been set up for a few months. I put a couple of damsels in after the life rock had been in for a month, but I think the blue damsel killed the other one. Then after a month the blue one developed popeye and died. It has been a month since the fish died and all the water levels seem fine, so I was going to try again.
