I have a discus that appears to be constipated. It is my fault, as I fed too much dry food that must have expanded in his belly. He is not eating, and was hiding. I hadn't seen him excrete any feces in a few days and I am pretty sure that constipation is the cause. I have tried dosing several times with epsom salt (2 tablespoons/10 gal), and that doesn't seem to have any affect. I did put a few drops of medicinal parafin oil into his mouth and watched him swallow some of it. He did excrete a little bit after that, but not much and is still really bloated. Any suggestions? I haven't fed him in a couple days, and doesn't seem to be interested in food, so I don't know if he would even try to eat a pea or other food soaked in parafin oil. I might be able to take some thawed frozen bloodworms, soak them, and feed them to him with a dropper to see if he will swallow it. I have him in a tank by himself, so please give me some ideas for treatment. So far, nothing seems to fix the problem! Thanks.
