Hello, I have 2 Fire eels, of which are length 7" each. These fish have recently come to consume 6-8 cubes of frozen bloodworm in a single night. Is this the normal amount, or are we overfeeding them? Here an videos of them feeding. Thanks.

I have a 2" blue moorii, 2" kenyi, 2.25" venustus, 2.5" borleyi, and a 2.5" jacobfrebergi. I know that the haps and the peackock are naturally predators, and that the mbuna need some veggie matter in their diet, but I don't know how best to balance them. I was originally using frozen brine...

Anyone have a technique that's worked for them before? Mines eating bloodworms no problem, but it would be nice to mix it up a bit sometimes. What works?
