I'm new to the forum but I thought I'd jump straight in with a problem I've been having.
My betta's anal and caudal fins have been getting spilts in them. The spilts are getting worse and I have no idea whats causing them. It looks like he's torn them but the problem is they are numerous (about 4 or 5 small ones on his caudal fin and 1 long split on his anal fin) and they are getting longer.
My tank is heated, planted, filtered, 6gallons, well lit and I do 25% water changes once a week. Noodle (my betta) is eating well and looks pretty lively.
Has anyone experienced these spontaneous tears, what's causing them and what can I do to stop it?
Any help or advice would be greatly appreciated.
