Would abso fish have it? Bifuran thatvis
Looks to me like it's internal parasites. I would QT the fish with Prazipro like Marrone recommend. Also, try to get your hands on Bifuran and soak it's food in it before feeding. I have been using this product for a while now and it has worked for, especially for internal parasites.
Ok, sounds like a plan. Thanks! I've started soaking the food in bifuran hopefully it helps
