Three weeks since I treated for flat worms, and they're back. Worse, Bubba the trigger has gone totally blind. I attribute it to the ingestion of dead and dying flat worms. He was chasing them around in the water column and eating them. I tried scaring him off the best I could, and caught up as many as I could with a fine net but I know he ate quite a few. I first noticed he was having trouble several days after the treatment. He was having trouble grabbing pieces of food. He usually gets more than his share at feeding time. As the weeks went by he was getting worse and worse. I started having to use a feeding stick and finally had to remove him to the QT tank. He is now totally blind and except for feeding time, spends all his time with his head in the rocks and his trigger locked in. I suppose the humane thing to do is put him out of his misery, but I wanted to be sure there is no hope for him first. I've been researching blindness in fishes, but can't find a whole lot of info. Anybody run into this before: I know the flat worms can be toxic but there are some fish who eat them regularly. Maybe dead flat worms are more toxic than live ones?
