Hi again, it’s Karen.
Pete is right. It doesnt sound like GBS. My horses floated at the surface and struggled with it for months before they died. Your horses seem to have something else!
It also sounds like perhaps they could be treated with a broad spectrum antibiotic. There are lists of them under the getting started, first aid link in this site. Crush the antibiotic in its tablet form and mix with tankwater.
Use feeder shrimp and gut pack them with the antibiotic using a syringe. ( i found it best to rip the head off of the shrimp first and then gut pack them that way). Your local vet should be able to prescribe the medications you need so that they are available to you. Also be careful not to overdose!
Also, your local aquarium should be able to test your water for you. A good marine aquarium should have all kinds of water tests for metals, phosphates etc etc. It may help to take the medication used along with you so that they can see what is in it. Also, try calling the manufacturer of the medication you used in your main tank. Maybe they know something we don’t. ???
Are you able to put your horses into a hospital tank at your house with a filter (sometimes an aquarium will lend you one) or in an aquarium to be minded which specialises in marines? Perhaps that is an idea? To remove them from the environment that is causing the problem until you know what is going on with your water quality.
I hope that some of these suggestions help. Sorry to hear about chloe.
