Please Help...

Need some advice and hope someone can help

My Sterbas Cory Cat seems to be swimming up to the waters surface and just hovering there...and he seems to be blowing bubbles? I am assuming this is not normal? He had a bacterial skin infection about a week ago which cleared up after treatment and he has been doing much better and seemed to be happy until this? He swims up hovers for about 5 minutes and then swims down finding food in the gravel and then swims up again? When he remains still on the bottom of the tank it appears as if he is having a problem staying down....his tail seems to float up slowly....? His fins are quite beaten up due to being attacked by the other fish when he was ill before I isolated and treated him...but he manages to speed around the tank without trouble when he wants....so I am assuming he is not having problems swimming due to his fins?

My tank size is: 2ft x 1ft x 1ft
My water stats:
Nitrite = 0
Ammonia = 0
PH = 7
Nitrate = 12.5
I have an internal filter with an aeration device on one side of the tank and another small air pump with an airstone on the other.....could there be too strong a current in my tank?

Any help or advice would be much appreciated

You stopped the med to soon before the bacteria infection had gone completely, start him on the med again, good luck. Increase aeration.

I followed the directions on the bottle exactly.....treat on days 1, 2, 3 and 6...am I suppose to just continue the treatment over and over? Do you have to wait any length of time before you repeat the treatment?

I treated the whole tank before....should I treat the whole tank again just to be safe or should I remove him and treat him separately?
