Seahorse

[blood_hound]

One of my tank looks kinda empty right now. Its a reef tank I got one clam , atleast 50 blue leg hermits, I have 5 fire blood shrimp in there ,2 cleaner and a peppermint shrimp, and for the fish I got 1 watchman goby, a maroon clown(soon to be move to the other tank) and 2 mandarin "which I assume dead since I haven't seen them for 2 weeks now"

Here's the question can I put a seahorse in there maybe 2or3 and where can I buy them localy?
