What's this?

I discovered this in my tank this morning. There is one other spot with the same thing on the other side of the tank. Both spots are relatively small, about 1/4" dia. Can anyone identify? Thanks in advance for any help offered!

Looks like sponge of some sort to me.

Pretty sure it's a pineapple sponge. Either way it's nothing to worry about.

Everytime I'm pretty confident I know what something is I find out I'm wrong. For my own knowledge how do you know it isn't a pineapple sponge?

Don’t worry about it. A pineapple sponge should be white and looks like a pineapple. Usually more common in newer tanks. There are thousands of different types of sponges and pineapple is one of the few that I can recognize and name.

I thought it looked like a pineapple sponge where you are looking at it from the end (kinda like looking through the hole in it). I assumed the color was due to the lighting in the tank.

Thank you! I am of the same mind but in this hobby you just don't know and by the time you do it's too late.

At this point I have to agree that it's not a pineapple. Wrong shape and color. Also, I have those and can identify them.

Thanks for the great discussion! I love this hobby.
