Minimum 2 Trios (2M 4F). These are some very nice delta guppies. They have dark eyes and they look very similar to Albino Red Deltas. This is a gold body strain (will try to correct lot name,sorry). This strain was original from an International Fancy Guppy Association member. They produce well. I use this strain to keep good color in my red albino line. If you plan on keeping good color and deportment in your guppies be sure to keep the different strains separate. If not, you will soon have a lot of guppy mutts. Nothing wrong with that. It all depends on what you like.
