i'll say 28. i have a 20 gal. freshwater tank that a pair would do great i all that is in there now are 2 little neons and they are lonly. hey if i dont guess right i might be interested in buying a few babies when they are ready to go. i'd rather buy them from someone who takes care of ther fish (not walmart) i shouldnt take that much to ship. let me know something . And good luck with the babies!!!!!!!!!
im going with 45
what's your method of keeping them?
is she in a separate tank, breeder or in a community tank?
a lot of the fish could be gona by the time u get to em
