I've had my 3 pigeon blood discuses for 3 weeks now and they're still hiding in the bushes. I was just talking with an expert who said they might have these parasites. He said to take them out of the tank, put them in the 30 gallon and observe them. My 30 gallon is up and running because I was planning on getting more discuses.......not now of course. He said to take half the water out of the 30 gallon and replace with water from the main tank. Both tanks are 86 degrees but he said once the discus are in the 30 gallon, to raise the temp. to 90. If they have a white discharge, then it's probably this parasite sort of thing. (can't remember the name of what he said it might be). I have to do this all tomorrow because I'm out today. I'm very nervous. I have 4 pieces of driftwood in the main tank and I'm wondering if I should take a small piece out and put it in the 30 gallon? Will it make much of a difference? Does all this sound like a good idea?
