I’ve been feeding them 2x/day. Still dialing in how much, but baby brine shrimp. I have two hatcheries (alternate them). Once the shrimp hatch, they get put in a cup with a mix of my 6 live phytoplankton mix. When ready to feed those, I put them through a 120 micron strainer and rinse them a little with tap water. Then rinse again with ro/di, then rinse them out of the sieve into ro/di (this is part of my top off) and dump them in.hey btw, how many times a day do you feed your horses and how?
