I've got a some tank raised percs that have been in the tank for right at 2 weeks now. They've been doing great, but Weds, one of them started laying down in the corner of the tank... and when he goes down there, he just lays, pretty motionless. When someone walks in the room, he swims up to see what's going on, but then goes back to his corner.
I did a test of the water, and the only thing odd was my ammonia. It was the first time I've ever gotten a traceable amount of ammonia since cycling the tank. I was just getting ready to do a 10% WC anyway, so I went ahead and did it. Yesterday, he was back up and swimming all over the place.
Today, he's back in his corner. All day long. I did another water test, and nothing wrong. Everything looks good. I'm testing amm, pH, trate, trite, SG, alk, temp and everything looks good. I even took a sample to the LFS and it tested the same there.
But when I put food in the tank, he comes flying to eat. Eats good, then goes back to his corner. No sign of any stress from ANY other critters including stars. My brittle is just as active (and hungry) as ever.
The guy at the LFS and I were talking and wondered if maybe he's just going to a happy place (I don't have an anemone for him) and hanging out in the corner like he would in an anemone. He doesn't look stressed, not gasping. Just looks sleepy or depressed.
I'm pretty much figuring just keep an eye on him and wait it out. I've got more water ready, and can do another WC, was thinking about trying that. Any thoughts?
