What's you pH? It may be a little on the high side for a CTs fins. Driftwood and/or IAL or Oak leaves might naturally lower it enough to straighten his fins. Of course then you have tea-colored tannins in the water. Some people like that. I don't much.
thanks =) do you know why his fins still curl? it looks like they are uncurling a bit but some just don't want to straighten out. x_x
oh no problem, I thought you would delete it. =) I would too. hahaha!
Pineapple is yellow scales with black scale-tips. If I see a pic, I'll show you. If his body color were blue, he'd be a MG (mustard gas...what an unfortunate description. Thai breeders don't have the background to know that). Color-wise, he's a copper---several layers of color that change when the angle of the light changes. But he's so clearly green..most unusual fish.
