Last week, I got a beautiful DTHM at Petsmart. He's settling in well, though we're having a battle of wills over food.
And he spends a lot of time trying to pick a fight with his own reflection.
This morning, I noticed that his top fin (I must learn the names of the fins!) is looking raggedy, just along the edge. He has one plastic plant (fairly soft, but still plastic), one cloth plant, and one real plant in his house. So I suppose he could have rubbed the edge of his fin on one of those, right?
BUT--what does fin rot look like? There's no discoloration there. It's just looking a little ragged along the edge, when it didn't before.
What do you think?
