Found this growig on the heater and small bits on the glass of the tank. I have drift wood in the tank so im assuming its some kind of fungus?

Should i be concerned?

I'm pretty sure they arent because its nothing like the ramshorn or bladder snails eggs that I get and its way bigger. Also when i removed it it was like a porous spongey thing

Could be a freshwater bryozoan, if you get another growth, it would be worthwhile to throw it under a microscope.

I wouldn't be concerned, but I would be curious. I've never seen that, which may be because I'm in a different environment. But that looks interesting.
