Hi I just got my tank setup a few weeks ago, and I got some fish for it about a week later. They've all been doing fine so far, except my yellow lab has started showing some unusual behaviour. He's been really twitchy, not quite swimming outta control, but just hovering and then he starts twitching. I have noticed him trying to scratch himself on some of the decorations and on the gravel as well. There is currently an ick outbreak which I just caught, so I'm trying the salt and temperature treatment right now before I start using meds. Does the ick have anything to do with this behaviour or is it something else entirely?
