best bet is to just go to wal mart and buy a 3 dollar breeder net its not that costly .....or go to petsmart and buy those other more fancy breeder things......oh and an idea so the fry/eggs can drop just make holes big enought hat the fry will fall through oh and put in some breeding grass if they are livebearers so the mom wont eat them well thats what i did and hey it will help in the long run
