Help i am i new user and i came home today and my 3" had this big lump on his head. I currently have a 55 gal with some drift wood and a bhudda statue. I have a 6-7'' st datnoid and the 3'' it datnoid in there and the big has been bullying the small one lately. He doesnt even leave the bhudda statues anymore just sits inside of it. And today i came home and he had this reddish kinda orange lump on his head. I have a 10 gallon tank but there are four 1'' to 1.5'' baby it datnoids in there and i am afraid to put them in with the big guy, but if i have to make a quarantine then i guess i will have to. any advice would be greatly appeciated.
