I have 2 angelfish, i noticed that they were fighting a bit but nothing major. Both have been eating and acting fine. This weekend the smaller one has been hanging in an upper back corner of the tank away from the other fish. He has not been eating and seems lethargic. I also noticed there is a white trailing string coming out of it, doesn't look like regular fish poop, just a long semi transparent string like thing. I don't want to lose him but it seems that if he doesn't start eating it will be a goner.
Water is good, Am = 0, Nitrite = 0 and Nitrate = 5-10, just did a water change. Tank = 50 gallons, Tank mates: 1 Krib, 1 other Angelfish, slightly larger, 3 danios, 6 small zebra danios, 2 parrotfish.
Thanks for any advice.
