I noticed bloat in my flowerhorn about two weeks ago. It was there when I fed him and went away when I didn't. So I treated him with Epsom salt soaked pellets, bloat was present then. Then I noticed white poop so I stopped feeding entirely and added metronidazole 400 to the tank. Didn't work as I only saw white poop, so I added the medication into his food and now I can see brown poop hanging from a clear poop sticking out of his butt. Earlier the poop didn't stick out of his butt. What to do?

Perform a partial water changes, 30-50%, using conditioned water. Dissolve 1 teaspoon up to 1 tablespoon of Epsom salt per gallon of water in a cup or two of tank water and gently pour it into the tank. This will work as laxative. Fast the fish for 3 days, then start feeding bits of cooked and shelled green peas until defecation and appearance are normal. You can also add metronidazole at 200mg/20 gal to the tank. Repeat the water change, salt and metronidazole every 3 days for 3 cycles. Be sure to treat only the amount of water being replaced with salt and not the entire tank volume. Remove the carbon filter insert during treatment as well.
