okay so the live rock that im getting has been in a tank with clowns and blue damsels for about 5 years now so im hoping it would be safe to put in my tank, and no sump and no power head yet unless i was planning n getting a fish that needed one its also a 30 gallon tank with one like hang on the side filter right now but if needed i could get a different one. but i was told by many people seahorses do not like/require a powerhead so i thought i may start with them. i also know i have to wait to get any fish or anything but was just hoping to get advice, and i do have time to feed the sea horses but still for a first time tank...... not a good iidea?
