What is this?

[desertio]

I was doing a water change on my 13 gallon biocube and in the back section I
saw these. does anyone have any idea why or what these are?

No matter how much I try to use my psychic power I just can't see anything. But if you attached a picture I am sure that would help kick it in gear.....

 

[desertio]

Ha ha. I thought I did. Sorry

 

[twilmot]

I am not quite sure, kind of hard to see but maybe bubble algea? Are they soft and mushy? or hard?. Hard to tell from the blue lights but are they white?

 

[desertio]

Soft, gelatinous, white/clear. I have never seen bubble algae that wasn't green. Don't thinks that's it.

Some type of sponge perhaps? Tapatalk pictures are crp. Try to get a better picture if you can.

My roomate has those in his tank and we just assume sponges.

Bubble algae is green under low to mid illumination, under high it bleaches like corals.

There isn't much light at all in this area. Usually pretty dark in there and it is soft
