It seems like the four with swim bladder issues are getting better. One of them is doing very poorly, and is much smaller than the rest of the batch, and lays on the bottom. I don't think this one will live. The other three are the same size as the rest of the batch and are doing well. So far I haven't lost any, and all are growing well. I have rigged up a good little BBS hatchery chain.
They are starting to eat Cyclopeeze and Coral Frenzy now too.
