Here's the baby I bought on Thursday:
Sorry about the poop in the photos, I removed it after I took them...probably should have done it before, lol. S/he is currently living in a breeder box in my sorority tank with a chunk of hornwort for cover and seems to be doing well. S/he has eaten everything I've offered: live ceriodaphnia (tiny tiny daphnia), frozen brine shrimp and blood worms, crushed up Omega One pellets, and flakes. S/he has been clamped on and off but overall is pretty active, seems healthy, and my girls are VERY curious about the newcomer. If it's a girl, it will join them in the main tank when it gets bigger. I do see an egg spot, but I've read that is not always telling of the gender. Maybe someone with a good eye can tell?
