Hi guys. I noticed one of my seahorses had what looked like gas bubble disease a few days ago. I put her in a hospital tank with Diamox, but I lost her yesterday. Today I found two dead seahorses in my seahorse tank. You can see obvious skin discoloration on one but the other looks perfectly fine. Wondering if I need to get the rest of my ponies out of there if this is something contagious? There was a major re-Aqua escaping yesterday, but I don't think that would have killed these two overnight.
