Stuck my four inch Midas with my convicts which vary in size from two the three inches. I rearranged the tank and such like I do with usually introducing new fish. He got beat up a bit because he's a pansy. But he's got a bit of eye cloud going. Is it something I should treat with meds and if so what do you suggest? My water perameters are all good the ph was a little low but it's fine now. It's a 60 gal tank btw.
