My betta is in a 6 gallon Fluval Edge with 3 Anubias plants.
Ammonia = 0
Nitrates < 10
Nitrites = 0
Temp = 81
He has one Nerite snail companion.
He split his tail badly flaring about 2 weeks ago. I hid what he was flaring at and put an almond leaf in his tank. His tail looked worse the next day so I put him in a rehab container with 1tsp/gal of salt (not AQ salt) and floated him in my big tank to keep him warm. I changed his water 100% every day and his fins healed after a few days. I put him back in his tank and a few days later he is shredded again!
He likes playing in the current, but he hasn't been flaring. There isn't anything in his tank that would tear his tail, but I'm at a loss as to why this is happening.
He's a veiltail.
Anyone have any ideas?
