ve three peppered corys, bought them together, but one has gone red under its skin, on its back and underneath, it is still eating and acting normal but doesn,t look right, has anyone any ideas, thx Mark
it sounds like it could be septasima
i would treat with an intetrnal bactaria med( interpet no 9 anti internal bactaria is a good one and so is myxazin )
iv used both of these meds for a number of things on my corydoras, id go for the interpet no 9 as i used it about a month ago on one ov my bronze corydoras with septasima and it cleared it up
let us know how it goes
it might be about 4-5 days before you see any improvement it is a 2 dose med but u might have to redose after the 7 days it says untill its cleared up
