My rainbow shark’s dorsal and anal fin seem a bit ragged, with the fin starting red, but the ragged part is clear/white. Is this finrot? An aggressive fish? Damage from decorations? Also, second question. What kind of fish is this? I was told it is a kind of botia that stays on the smaller side at my lfs but I can’t remember what kind they said it was. It is about 2 inches long and I got it about a week and a half ago. It was about 1.75 inches when I got it if I remember correctly.
