Clownfish acting weird

[koor]

Over the past month or so, my tank has had a ton of issues. I lost a lot of coral and inverts. I moved the remaining coral that looked somewhat alive still into a QT last Wednesday. I also sent an ICP at that time. I will include those results. The last couple of days my two clownfish have been acting weird. Decreased appetite, slower swimming, and they will now just hover in place. First it was up in the corner by the overflow vents, now it is in these rocks. Is this cause for concern? When I moved my coral to the QT I moved my ai prime HD from my biocube to the QT and put the stock light back on the biocube. Maybe it could be the light, but does this look like cause for concern or just a clownfish being a clownfish? He will sort of lay on the rock for like 30 seconds at a time then come out and swim around then go back and lay on the rock. As I’m writing this I just saw my second clownfish lay on the rock on the other side of that small crevice the first clownfish was laying on. I just saw both of my them doing the mating dance yesterday.
Any help and insight is greatly appreciated. I want my fish to be okay! Only other live stock in the tank is a tailspot blenny and a few trochus, cerith, and nassarius snails, and a scarlet reef hermit.

Nothing in you ICP results shows critical for fish.

Is the blenny eating well and behaving normally?

Do you have a way to measure the pH? Can you take two readings for us - one before the lights come on in the morning and then another reading in the later afternoon?

Yes, I can measure pH. Lights came on about an hour ago. Should I measure now or wait until tomorrow morning for the lights out reading?

The blenny is acting normal and eating well

I'd wait until tomorrow morning. What I'm trying to rule out is any sort of a gas exchange issue with the algae and aeration in the tank. It may not come to anything, but it's easy to rule out by simple testing.

Yup, that’s what I was thinking too. When I first noticed the weird activity with the fish I took my skimmer cup off and have been running it with no cup since to add extra oxygen to the water. There is a bit of cyano on the sand and rocks. Could that affect anything? I’ll admit I’ve gotten lazy with keeping up with it
