Last night, when buying a heater for one of my older betta, I impulsively bought this guy--Zar'roc is his name (we name all our fish after swords) and not only can I not really identify what color he is, I'm concerned he might have fin rot?
He's seemed pretty healthy so far, is pretty active and eating well, but I don't want fin rot to get serious if it's mild as is.
Is it normal for them to have spots like that? None of our others have been dotted quite like that, lol.
