If you can get a pond, the comets will be happiest!
Don't laugh, I read in the "Why you want FW
" thread, someone started out with a 10 gal
& 11 months later ended up with a 100 gal
pond, plus assorted tanks!
Seriously, why don't you take the 10 gal
the comet was in, and use that to house 2 or 3 of the babies. The 2 black mores will do fine in a 10 gal
for probably a year or more, although ideally they shoud be in a 20 gal
once they get to be 4-5" big.
