Well... another female holding.
But, we lost a male. We dont get it. He started breathing hard one day and was dead the next.
We put the 8 or so fry/barely juvenile into the 150 with the adults. So far so good. All survived the night.
The holding female is now in the 20 gallon by herself and there are still a batch of fry in the "overflow" holding tank on the side of the 20 gallon.
Hopefully all goes well!
