I've posted some pictures on the baby aro thread, but I will post some here soon.
Some behavior that I have recently noticed:
After about 4 days in the 125 gal, they are making themselves at home and feeding greedily on frozen bloodworms.
The problem now is that they are displaying more aggressive behavior, there are a few missing scales and so. I've noticed that 2 of them (probably the dominant ones) have the most scratches on them and also are patrolling their own little territory like space.
The other 6 are more distant than they used to be, but when scared they gather back into a shoal. There are also 2 that tend to stick closely, I don't want to say they're a pair as they're only 4" but they're probably the weakest of the bunch and so tend to stick together.
Despite their aggressive behaviors, they don't seem stressed or anything.
Does anyone have any suggestions as how to go from here?
