I got a
royal gamma 2 weeks ago. I kept it in qt for a week and moved to main tank. He stayed hidden first couple of days but now comes out fairly often. My question is he has a "bruise" on his forhead. First noticed looked like a scratch but now has darkened. He eats well and is active, no scratching. Some of his hiding spots are tiny and wondering if he is just rubbing up against rock. Would you just leave him be as long as it doesn't get worse?
Also, can someone explain what a freshwater dip is and what its purpose is? I have seen alot of people recommend for different ailments.
