Ok, I am tired of the wifey nagging that she wants this, she wants that, but I alwys end up having to tell her that she cant get that in this tank, either because A: its not a reef safe fish and will go after everything eating it all up, or B: because again its a reef tank and it is a different type of setup.

The three types she loves are Lion Fish, Jelly Fish, and Sea Horses. I wouldnt mind setting up a Nano Jelly fish tank or a Nano Sea Horse tank. But I need pointers on both. Type of tank, minimum size of tank, parameters, type of water movement, lighting, etc?

Thanks
