That aiptasia is in a perfect place to hit it with aiptasia x. Look very closely at your tank, where there is one, more are likely to be. Look from all angles. Start killing them now. They're not the end of the world, but the sooner you attack the easier eradication will be.
As far as cyano goes, been battling it myself. It likes dead spots lacking flow, and dirty water. It will not go away on its own, so turkey baste liberally, weekly water changes. Syphon it out, change mechanical filters daily, feed less, ect. When it's on zoas I just blast them with a baster to never let it cake. Also not the end of the world, but you MUST actively try to beat it.
