Need help identifying something!!!

[Magicfan1423]

Hi all,

Have a 55G Freshwater set-up with 10 Giant Danios, Pleco, Swordtail, Apple Snail, African Clawed Frog and Senegal Bichir.

I noticed a weird substance growing on the back of my tank and I took some pictures of it. The strange thing is that it's moving! It slowly is moving around the sides of my tank. Please someone help me identify it so I know whether or not it's some type of algae I need to eradicate or something else..

Its a slime mold! Theres actually very little information available on them but its something I came across months ago when searching for something else entirely and someone posted on here about about it the following day. They are actually quite fascinating! Heres the thread with the link to pics/info: An odd growth help! - Aquarium Advice - Aquarium Forum Community
