521 babies!!!

H. reidi, like many pelagic fry, aren't large enough to be taking the brine nauplii so for the first part (for me it was the first two weeks) rotifers or small copepods fit the bill. As it is harder for sustaining copepod cultures most depend on the rotifers as the main first food. I usually went with a mixture of rots and brine for the second two weeks, before going just with brine after that.
I use Dan's Feed for enrichment of all rots and brine.
 
Yea the bubbles do seem to affect their swimming. It makes it hard for them to dive, the ones with the bigger bubbles can't dive at all. They just hunt at the top which I can't see them lasting too long that way.
Does else have this issue?
 
I had the bubble problem with my H. reidi, and I found that by having enough open ended air lines going so that the fry couldn't stay at the top, they eventually outgrew the problem.
While the fry couldn't control where they wanted to go because of the bubble current flow, they still continued to snick up the food as it passed them by.
So far, I've never had the bubble problem with the H. erectus.
 
I have a five day old batch of H Reidi, I am cutting back on the rotis because most of them have been eating fresh hatched bbs since day 2. You can see most of them have bellies filled with orange bbs and you can see them eating the bbs.

Very few have died so far. May be due to health of my male.
