Hey guys, I finally had the opportunity to pick up a paratilapia two days ago. I only payed 8 dollars probably because he has some kind of disease. I don't know what it is. I thought maybe columnarus but he's been alive for a while and I know that it is a quick killer. I'd love to keep this guy alive if I can since they are hard to find around here. And 8 dollars is a verrry good price. Been treating with melafix, pimafix and salt for 2 days in a 5 gallon sterilite tub. Any ideas what this possibly could be? He seems to be acting normal and I've seen him eat everything I've given so far. Thanks in advance.
