Yoke is also in tack on BBs for the first 12 hours, thats why you have 2 batches going. After they start eatting the baby brime shrimp good. they can be pulled off mom and dad. I 2 have raised some large spawn or 2. 300/375. That pulls mom and dad down bad just in a couple weeks. I have a picture on Kennys site of won of my big fish that spawned a couple times this week in my main tank. SHE dropped 500-600 eggs each time. Jerry
