I'm totally new to this forum, but I thought this was the best place where I could get advice. I believe my new male halfmoon double tail may have fin rot. Or maybe a possible tail biter? He does have a split in his top fin now, but that might be caused by flaring at my female?
My other male has split his tail fin because of this, he flares at everything.
Anyway, my half moon is in a small half gallon or so 'hospital tank' for 4 days now (that's how long I have him) for a quarantine.
Right now I have a 5 gallon divided with a male and female, but in about a week I'm getting a 10 gallon to divide for the 3 of them, if they all are healthy. He's very active, eats like a piggy, swims fine, has been blowing bubble nests. It's just his tail seems a bit odd looking to me. Unless that's how it's supposed to look?
If anyone could help me out, I'd greatly appreciate it.
