a few days ago i moved my fish into their new 20g long tank. i used their old filter and a new one. they did lose the gravel from the old tank (left it in the old tank which is now split with 2 bettas) so they lost some bacteria, so now the tank is mini-cycling. i am doing daily water changes to keep the levels as low as possible.
my red honey gourami, the day after i moved him, i noticed a small black spot on his head, just above and behind his eye. i kept an eye on him, and the black spot got larger, and actually seemed to move down towards his eye, and then dissapeared. now tonight, i checked on him, and it now appeares that the area behind his eye has a large hole. its about 1/16" diameter, but on a 1 3/4" fish, that's a good sized hole. he is acting normally, chasing the tetras, nibbling on the plants (he's never gotten over his shyness enough to compete with the tetras for food, so he eats whatever they miss and algae off the plants) and swimming around and hiding under the heater. i know it can't be HITH because that only effects large cichlids, but it looks like a big pink scar on his head. i can't tell if its actually indented into his flesh, but there is definately something there.
should i treat with salt? i will get some melafix and see if that helps. anybody know what could have caused this?
