I think Bela has improved but whatever's wrong with him (my best guess is still that it's a fungal infection) is making him a bit listless. He's spending a lot of his time resting on the gravel -- which he's always done, it's just that now he's doing it a bit more. I'm torn between worrying about him and wanting to laugh because with his feathery fins spread all around him and his head resting on a marble he looks like a lady on a fainting couch.
I'm going to try him on aquarium salt and Rid Fungus tomorrow after a trip to the pet store. All the kids seem to think highly of Rid Fungus.
