I am excited to say I have my dream coming true. I just set up my 90g reef ready tank and I am going to make it a seahorse tank. I have upgraded from a 37g to this new tank and used all old live rock and cured pukani live rock(did it myself) I am wondering how many seahorses I could do(erects) and how long I should wait for them to be added. The first time I had them I got 10 and added about 6 weeks after fully cycling the tank. They all lived and did very well. Here are some pics of the new tank.
