He still alive. I just changed 2 gallons of water. I am not feeding them because I think it could be the pellets I put on the fish tank as well. There was a lot of left overs in the bottom, even though I have a pleco and 2 more to eat from the bottom plus my shrimp, I think I put too much, so I vacuumed and I did not give them food today. I am getting the driftwood and boiling it right now.
