I’d help needed

Hey guys/gals, any idea what these could be? My first thought was sponge, but not too sure as they don’t seem like any we have in our other tanks. The big glob was discovered right next to one of our rock flowers which seemed to be acting kind of weird last week. Then comes blob 2 and 3 also found near the rock flower. They are squishy and seem to kind of slowly move a little. Our clown trigger was acting strange for a couple days and sleeping right near there and is now dead. All parameters are on point except a tiny increase in nitrate which is at 20 now.

they are squishy and seem to grab gravel.

I see poriferan sponge and tunicates which are filter feeders
