they dont seem sick and one of them i have had a fair time now ..today i got a second one its a lot smaller but theres been no truble with the fish i have in the pet store it was swimming rownd a fair bit but when i got it home in my tank it dose not move as much and spends a lot of time Vertical at the top of the tank the reson i only now found this strang is cuz the one i have had for along time dose the same thing and always has i thort it was just him but the new ones doing the same thing could the water be to warm or cold or some thing ??as i said they dont seem sick (oh the other fish i have are all swimming fine and normal)
