Black Convict Cichlid Emergency

[Drip&derp]

So this may be a little hard to read because I’m rushing.
My black convict is probably a year old now. I️ just did a water change yesterday. He usually hides from me or flairs then swims away and I️ don’t know what’s happening
I️ took a video and I️ have no idea what’s wrong.

Something is irritating his skin. Perhaps the water has something in it or there’s stuff on his skin, either particles or parasites. Did the tank happen to get a little dusty during/after the water change?

I️ did the water change hoping that it would stop

So he was already twitching before the water change?
