And to put it out of its misery???
It's flailing about on its side, then going still and floating up, then flailing about again, it looks like it's in agony and I'm a bit concerned, especially don't want DDs (6 and 3) to see it like this if lasts until morning? Also, the other fish in the tank seems to be trying to nibble on it!
Sorry I know this is probably trivial in the grand scheme of things, it's too late to contact anyone and DP is out, just don't want DDs to be distressed seeing it like this!
TIA
