Pineapple sponges in Pump Chamber but not Display

[ZzyzxRiver]

There’re pineapple sponges galore in the pump chamber of my AIO, but none at all in my display tank. Are they yummy treats for somebody?

They only grow in dark areas......sumps, pump chambers, etc. Sometimes you will find them underneath rocks in the DT. Some species of fish will eat them (I have seen angels and triggers both eat them). I can't say for sure anything you have will though....emerald crabs possibly?
