I am getting a brand new tank for Christmas. Currently, I have a bunch of guppies in a filtered and heated bin of water. I have 4 female adults, 4 male adults, about 20 juvenile guppies, and about 30 fry. I have the opportunity to give as many guppies as I want to my uncle. (he's using them as feeders for his cichlids) Here's what I was thinking: Keep the male adults and the promising-looking male juvies in my display (16 gal) tank along with a single swordtail and dwarf gourami with ghost shrimp to clean the gravel. First of all, are all of those fish compatible? I don''t want my prized male guppies to get terrorized. Then, I guess I could keep the two biggest female guppies in a quarantine tank used for raising fry. They would basically live in there and I'd throw in a male when I want a new batch of babies. All the fry and whimpy looking juveniles would go to my uncle's cichlid tank. My second option is to let nature take its course by putting all the guppies and their fry into the show tank and there would be a constant supply of food for the gourami and swordtail. However, if DGs and Swords don't eat fry, then I guess I'm SOL. Tell me what you think.
