I have 7 fry plus the pair. They all eat bbs but I do see copepods and worms on the glass sometimes. I have a paramecium culture and with a small pipette added when fry first hatched. Tbh the newly hatched baby brine is perfect for them. I alternate 2 hobby brine shrimp hatchery. I feed bbs 7, 8:25, and 10:45 am. I really like the hobby hatchery because you don't need a heater and don't waste brine shrimp. It took a little time to figure how much eggs to add but I got it.Amazing! How many do you have now and how are you keeping them all fed all the time? BBS, moina, paramecium?
