I chopped some bloodworms finely, and mixed it with rotifers, and Garlic Guard and they seemed to eat that. On the downside I have at least 7 of the 18 are goners... adding in the two that died before I picked them up at the shop that's half dead. They are way too young to be shipping honestly. Some barely even have the "nose" yet... they are sensitive species as it is, at this age, Captive bred or not it's just too young. I'm really disappointed. I knew they'd be small but this small is just ridiculous. I never lost any when I had wild caught until several month later from parasites (I didn't treat them soon enough because I was worried how they'd react to wormers since they can be sensitive to medicines.)
