Tuesday i picked up a 3" Datnoid from a LFS and he seems to be stressed. He's in a growout 55gal with 2 tiger oscars that are the same size as him. There is some rocks and a tube for cover and he's always in the tube. So yesterday i took out the tube and all he does is lay on his side. When i stick my hand in the water and pick him up he flares up in my hand and will swim around a bit and then just lay back down. I've had oscars in the past show this behavior when stressed but no other fish that i've owned has reacted this way. Is this normal for a juvenile Datnoid????????
