Right I know all that. (including the freezing) i guess I failed to mention that it's a small filter-less tank... I just threw 'em in there. But they usually last a day or two

Anyway, I left him overnight in a container with all the living ones (6) and two dead ones that came out with the net.

HE DIDN'T EAT.

All but one of the 6 guppies somehow survived the night, so they were floppin' and swimming all night. (why didn't they survive the tank I put 'em in?)

Now what.

I guess I'll try the earthworm trick you mentioned, Steve, And wait another few days for guppies again.
