Looks like a mucus sack from a sleeping fish. Was this pic from the morning time?

And is that a crack in the bottom left ?

Wow, the one on the left looks like Eeyore from Winnie the Pooh. I've never seen anything like that, sorry.

I can’t unsee that now, haha. Yeah, I’ve never seen anything like it either. I think the posta above are a good place to start, is it there all the time, or only at certain times? Is it spreading or moving throughout the tank, or is it just staying put?

i don’t think it’s cyano because it’s more black than red.
ammonia:0
nitrite:0
nitrate:9
alkalinity: 9.5
calcium: 415
salinity:1.025

More than likely a bacterial bloom if nothing is in the tank. I would let it ride for a while and see what happens IMO.
