White patch on rock

[oicu2]

Hi everyone

I attached a picture of something strange on a rock in my freshwater aquarium. It's the patchy stuff under the rock. Could it be snail eggs? It started as a small patch but seems to be growing. I have a ton of baby snails in the tank. The white stuff is on the gravel substrate as well. A couple of the pebbles are sticking together in a tiny ball with this stuff.

Is it slimy? I would take it out and rub it off, and then sit it in a 50% water and 50% household hydrogen peroxide for awhile.

There might be decaying food in the substrate causing a glump of stuff, I didn't see it. You could scoop the glob up as well and put into the peroxide mix too.

Snail eggs are a clearish to slightly tinted glob usually a circle like a pencil eraser to slightly larger to teardrop swipe shape. With little tiny dots in it. For pond, bladder and Ramshorn snails.

Mystery snails have a pod of eggs in a cluster white to pink peach color.

Assassin snails have a tiny square looking egg, and Nerite snails have a sesame seed looking /shaped egg. Both these types are individually laid.

Thinking it is a fungus growing there.
