Is this a sponge?

[Shifter]

I'm trying to get some help to ID this. I noticed them in the rock work also. I seems to be growing quickly and in several places. Any ideas on control?

I'm thinking of a number of sponges between 0 and 3...

Thanks. Not sure why it didn't upload properly.

Sorry, life got busy and I forgot about this post - yeah, those are sponges. If they're getting out of control, here are some ideas:

The best way I've heard to control sponge growth at this point is to use a steel straw to scrape and siphon out the sponge you want to remove. Sometimes you can create bad conditions for them and kill them off that way, but that's typically much harder and not always effective.

Some other sponge removal methods:

Generally speaking, the easiest way to remove sponges is to scrape them off (the best recommendation I've seen for this is to scrape it off and suction it out).

Other suggestions include exposing the sponge to air (obviously not a guaranteed solution, and definitely not viable for this situation); hydrogen peroxide dipping the sponge (again, not viable here); injecting the sponge with hydrogen peroxide, vinegar, boiling water, or air; microbubbles in the display; and a few more. Predation is not usually a good solution for this issue

Thanks for the information. I really appreciate the help with my first aquarium.
