I agree. I'm seeing quite a few little sponges and maybe some pods. If it's a newer tank, the sponges seem to dissipate over time. I wouldn't worry too much.

Thanks guys, tank is 4-5 months old so still pretty new.

There will be phases of what ever adventitious creatures pop up. Basically filter feeders that die off eventually when the algaes take over.

Sponges harmless filter feeders, I can guarantee there’s some under your rocks in the dark/shaded areas.
