He was inside the suction of an Aquaclear Powerhead that can be added/removed from the pump. There is a grate that prevents actual contact with the impeller, but when I came down to the tank this morning he was missing. I found him bent into a U inside the pump suction ben t into a U. I initially thought he had died and been sucked up there, but as soon as I removed the fitting he shot out of there like greased lightning. He hasn't eaten and is lying about on his side, kinda belly up at times. He is already in QT on day 12 of copper treatment and medicated food. Is there anything else that I can/should do for him besides wait and see? He WAS doing great... has been eating really well and gets along with his tank mates...
