I just went through the Seahorse process, and I failed.
My LFS set me up with a 5 gallon tank, small live rock, a branch that he could attach too, and live sand. Said not to add anything else for a couple of weeks. I could not get him to eat......Very very picky. nervous: I was trying brine shrimp. After a week the LFS said he could be lonely, so that is why he was not eating, so I bought another. Least to say neather would eat, and they both bit the dust.
So if you give it a try.... make your LFS feed the seahorse before you take it. So you know just what he is feeding him, and that he is eating.
Best of luck!!!:sleepy:
