I am always more than happy to help!
What breed are the seahorse fry? If the brine shrimp are too large then they will need to be fed enriched live rotifers. If they have not ben eating you don't have very much time
I have some in stock if you need them and I am in Southington not very distant! What type of set up do you have the fry in
Hope to be of help
