http://forum.aqua-fish.net/ A forum devoted to aquarium fish, plants, techniques and fish keeping as a whole. en http://forum.aqua-fish.net/?topic=angel-fish-in-trouble#1 I have a 50 gallon tank with two angel fish (which I have had for 3 years) red tail shark sucker fish and a huge gold fish. Recently one of my angel fish has started swimming flat and stays at the top he seems to be in distress. If you open the lid he will swim to the top only to float back up. He is eating but stays side ways. Someone told me they thought it was a bladder problem and nothing I could do it would eventually die. Is this true? Any thoughts??? Thanks bwaugh78 2013-07-17 http://forum.aqua-fish.net/?topic=angel-fish-in-trouble#2 That is a bladder problem which unfortunately cannot be cured. irwin id 2013-07-27
