Anything is good with clowns. Mine love my torch's over my frogspawns and hammers. I have even had them hosting to a hairy mushroom coral at one point. I personally like LPS and softies in a nano tank, lots of movement and flow. I see why people like SPS in their larger tanks, and as soon as I can get some better lighting, I will most likely start the change over. It might be still too early for a nem, you most likely will still have a few algae blooms, or at least one more at around the 6 month mark. But it is entirely up to you on what you choose. Just here to give IMHO advice.
