I have a Maroon Clown, NasoTang, Majestic Angel and a High-Fin Snapper in the tank. Prior to the addition of the sailfin everyone was in excellent shape and quite content.
will be most of the problem. Too many large growing territorial fish. In the absence of LR
for the fish to establish territories, this can be even worse as each fish tries to establish some type of pecking order (dominance). In a 125 gal
, you are best off with only 2 large species, a 3rd is pushing it and the final 4th is most likely instigating the aggression.
The Sailfin has been in the tank for about a week and I have noticed huge chunks of fin missing from my clown, a few nibbles from my naso's fins and a few nibbles from my Angle's fins. Anyone have any thoughts or suggestions - should I get this sailfin out of this tank? Is this typical behavior? Is this an adjustment period?
I would remove the last addition if it's been a week and no lessening of aggression. Typically there will be a few days of tail slapping and chasing but after this much time, you may end up with a dead fish or at the least sick/injured.
