Long Story short, my established seahorses were looking stressed once I added a new pipefish, clownfish and 2 baby seahorses. The pipefish, clownfish and one of the new seahorses all died from what looked like some sort of infection. I pulled my two large ponies and the last small seahorse to treat them in Furan-2 just incase. As soon as I put them in the new setup it triggered the release of many little babies (FRY).

I have no idea how to raise the fry!! Anyone experienced? Can help?
I would like to save some of them if possible...
Now I don't know if I should treat the tank with Furan-2?
