Sure thing — I’ll be happy to send you copies of those references. You should have them by the time you are reading this post.
It sounds like you have worked out a very good feeding regimen for your newborn seahorses with the help of your son, and I hope your prolific ponies and their offspring continue to prosper.
Yep, I think a hang on refugium is worth a try, and if you can build up a sufficiently large population of copepods and larval shrimp, it may help increase growth rates and overall survivorship.
Best of luck with your seahorse population explosion, Cheryl!
