Tank Crash - Fish Breathing Heavy..

[Nano]

I remember being told that herbtana makes microbe lift, and something else(sorry the name has slipped my mind) but combined the 2 make an excellent stress coat for just such situations. also I agree with the above, do an airstone to help bring some more O2 into the water, I did this when my canister on my cichlid tank broke down, I had about 4 airstones in different places to help keep O2 in the water. no fish lost!
