I have had a 10g tank for a few months now and I've seen a few fish pass and many that look as happy as can be but this is the first tank I got and I'm still very new to this. I currently have two albino Cory and one of them keep just laying on the rocks in the tank and not really moving much until a fish comes by he freaks out and swims away really fast or straight up to the top of the tank and then comes back down.. he still has been eating but I've never seen him act this way.. I am treating for ich and about two days ago the last sign of ich went away and I've been treating it at half the dosage the whole time. Please give me any advice you have
