now, we have to deal with the rest. this is a 20 gal, right?

    if you still have, like, 60 or so fish in there, you may have to...*gulp*....CULL. yes, i've said it. it will be hard and heartbreaking, but it will be necessary. if i were you, i would take the 15 i wanted for breeding, twice as many females as males, and, err, peacefully freeze the rest.

   freezing is the humanest way to euthanize. you can also use ice water, but i think it would be easier on the person to put the poor things in a jug of aquarium water, and put it in the freezer. then, the next day, you can take the jug and throw it away.with ice water you would have to watch them. i know i would. then you would have to pur the dead fishes and the water down the toilet and pull the handle. maybe you could do a combo? ice water in a jug, fish in jug, jug in freezer. next day, jug in trash.
