Hi Everyone - I have these white puffy things that look like there is a tube in the middle of them growing on the back glass, but can't find anything about them online. Does anyone know what they are? I'll try and get a picture to post.

Sounds like pineapple sponges - I have them too. Not a problem as far as I know.

That's it! But mine are white...I found a picture of a pineapple sponge that looks more pineapple color. Are the white ones still called pineapple? I'll do more reading too....thanks for the reply!!

Wow! What a timely post for me; I found the same things in the back of my biocube when I took it apart to get Chubby, my mandarin, out of it. When I googled the image it was confirmed. Glad to know they are harmless. I also learned that pineapple sponge is a pretty horrid combination of pineapple jello and marsmallows, and that Sponge Bob lives in a pineapple.
Thanks for the info!
Helen
