My 9 inch Sliver aro has been totally listless the past two days. THe only change lately was the addition of a 9 inch IT to the tank two weeks ago. The IT does chase the aro but causes no apparent damage. The blood parrot in the tank may be getting ready to lay eggs and has been bullying a little as well. Again; no damage from her little mouth. Could stress be causing the bahavior or could the fish be suffering from trama from the tank lid or side the tank tring to escape. He is upright. Not eating. Just bobbing in the corner near the top. ANyone have a similar problem? THanks!
