So I bought a beautiful new HM yesterday..
He seemed fine when we got home. I put him in a 1.75G critter keeper with a heater. I use Prime conditioner. This was probably about 14-15 hours ago.
I check in this morning to feed all of my boys, and he's just sitting at the top of the tank. He isn't really breathing heavily, from as far as I can tell, but he won't eat. He also has no reaction if I put a finger into the tank. He just doesn't want to move, and I can't prod him to swim around, really.
Should I be worried? What could it be?
He has no outer signed of issues that I can see. No problems with his fins or on his scales. No fuzzy patches or cloudy eyes..
I want to give him a water change, in case it may be the water, but I'm afraid a big change like that may make him worse.
What would be the best course of action here?
