Ok, so this is looking easier than I thought then - one powerhead, one HOB
and plenty of live rock and sand and all should be good!
Should I stick with the filter media that I assume comes with a HOB
, or should I remove it and replace with something else?
Oh, and I just looked up the fish you recommended - oh my god, little bit in love! I think I've seen these for sale but usually really tiny. Ridiculously cute - maybe even better than a lionfish! I take it it would still be only one in a tank, due to their eventual size and, I'm assuming from the look of them, aggressiveness?!!
