Hi Jennie,
Its my understanding that zoos feed on phytoplankton like DTs (which is what I dose). Sometimes I spot feed them with a little baster and sometimes I just pour a half cap into a high flow area. I also dose Cyclop-Ez on occasion and they seem to respond.
My mushrooms seem to take just about anything fleshy I put on top of them such as little pieces of shrimp, scallops, etc.
What about everyone else?
