Black Sponge!?

[Clown_goby<3]

Just curious if anyone knows what type of sponge this is ? 😊

I have a black ball sponge that has been growing in my 10G for almost six months now. It's harmless so far.

Does black ball sponge ever grow in a tube like shape?? I'm not worried about them being harmful I have some pineapple sponge that I love, the black ones just seem to be growing upward and I cant find a picture of anything similar to ID it

Mine retained the ball-like shape. It's quite unique actually because that system I have it in is a simple FOWLR with only two fish and no CUC. It just popped out of the blue one day on a loose LR rubble and has been growing slowly ever since.

I've had ball sponges before they pop up then go away these guys are growing slowly but they are growing in multiple areas of the tank. I like them so I  will just leave them be. 😊

If you want to encourage sponge growth you can dose small amounts of Creatine Monohydrate (the bodybuilding stuff) at like a pinch or two every couple of days, they love it and really explode with growth.

Oh that is interesting, I never would have thought! I would if it was a prettier color Haha They are great little filter feeders and arent bothering anything in the aquarium. Fun little things. Thanks for the tip!!
