Maria I've not had him long at all. He's a rescue and unfortunatley was rescued by someone who knows as much as she could gather in the week prior. But I'm trying to keep up and attempt to get this guy not to bite me. Please. I'm just changing your water.

and Kaorte, I have live plants in there and there's a significant ammount of substrate above his hot side.... should I put the prob to the glass still, or perhaps an inch under the substrate?

Thanks!
