I am sorry that she didn't make it but you did what you could. Sadly lfs are not always knowledgeable about seahorses and how they differ from other marine fish.SHE DIDNT MAKE IT it like I said it wasn’t a big deal she was free the store wasn’t doing anything I watched her at the store for a day before I asked to take her I gave her small dose of stress meds and an air pump with algae there was never a plan to put her in my main tank with the clowns and inverts I said I would work out the details later as for the hostility I was looking for med recommendations and how to get her more active to eat if she was already to far gone there was no point in trying to prep her for my tank so I got a bucket an asked the guy to give me more water that she was already in I guess I need to type every little detail before asking just everybody relax the real killer was the dummy that put her in with the super aggressive tangs
