Thanks, I have kept bichirs for years and never ran into one that acted like this one. My Jurasic fish book was the one that said to use malachite green at 1/2 to 2/3 the dosage to help with progressed cloudy eye. The stuff I bought just happened to have formalin in it. I only used it for 2 days. I just got done putting 5 pieces of cut up night crawler in the tank with all the lights out in the tank and house. I won't know if he has eaten any unless he shows a bulge in the morning. I would hate to loose him. I have never met a bichir that won't eat when food is dangled in their face. I use a thin rod so that my hand is not in the tank. I just poke it through the food and stick it in their face. My other two bichirs which have been with this one since day one eat like pigs.
