I have a 10 gal tank w/ 1 balloon molly, 2 blk/wht mollies, 1 calico molly and a "evil" orange molly. All are suppost to be females yet I still don't know how to tell. That would be my first ? anyone got good pics to show the differnce. Next ? can I feed my mollies blood worms or brine shrimp? right now they only get flakes. Also I read on a forum which I can't find now about a gavid?spot on the pregnet mollies... can someone tell me more about this. I did have one baby this week. not sure from who yet but have put it in a breeder container in the same tank and seems to be doing good.
