There was a little bit of a smell, but I did a full tank clean when I noticed it, and it hasn't came back. I feed them about 5 crickets each, but sometimes I have to put more in so Kevin gets some. The wood is malasian driftwood from my local aquariam that I washed heaps, boiled it, then baked it.
He was acting more lively today, and was hopping around, and eating more so thats good
