Babies eating daphnia

I found out yesterday that the daphnia that I had put in a couple of tubs last month and forgot about in the garden have been thriving.

We took the lid off of the tub yesterday and there were thousands of daphnia in there. I decided to try the babies on them and they loved eating them.

I have done a water change again today and given them more daphnia and also baby brine shrimp and the babies are darting around the tub like no-ones business.
