Just moved my FH from his 50g to a new 75g. He isn’t as active and not eating well but I just made the move 24 hrs ago so I’m not too concerned with this yet. But I noticed a small bump that just popped up at the base of his Kok that was not there when I moved him. Is this something is should be concerned with. May be nothing but this is my first FH so don’t want to take any chances. Tia
