Yeah, it seems that general consensus is to just let it do its thing, dont change much if only a few are acting up; specifically since its still young. Plus look for more fish!Ah. Yeah that is going to be a relatively volatile biome for a while longer. At least you started with live rock, so that should save you 6-12 months.
My current build thread is essentially an insta-tank with all live rock, a ton of fish and full mixed reef population in 3 months. Can be done. Only a few SPS specie couldn't cut it. A couple acropora valida colonies and all the pavona maldevensis died early. Everything is still plowing along just fine. Heavy fish load with many herbivores.
