Ok ive had my midas for over two years now and hes never even had ick, well i had three small clarias cats in with him and i just noticed they were swimming around him biting on him and over all harassing him. Needles to say theyre now gone. The ends of his fins look a little chewed and he has what looks like could be some infection. It seems to be a little swollen on the one side at the base of his tail. If it an infection or could one of the clarias have spined him?. Also what do you recomend i do, if anything. This is my favorite fish and if i lost him id lose it, hes been my prize fish since the day i bought him so please help.
Heres some pics i took to help.
