Is this a safe transfer..quarantine to main pond???

The found floating doesn't seem right to me.......
It usually take over 24hrs for the gasses to build up enough for them to float-
if you have any botttom drain action.

You Don't need to take a year off buying over it Pt Loma ponder.

If 4 deg F shift was deadly none of mine would have lived. I can honestly say I've transferred fish with temp variations of 4-5 deg up and down with never so much as a blip on the radar. I'm with Mike and Mike. There had to be something else going on with water chemistry to have that result.
