Hey all, I have these 2 spots on the side glass of my biocube 29, they are bright white with very purple rings around the outer edges on their side that's attached to the glass. Sorry for the poor picture, but they're small, about the size of the opening of a clicker pen (just a pen you use to write that you click the end to bring out the writing part), and my iPhone won't focus on something so small when it's close...

Corraline

Hard to tell by the pic but it could be coraline. See if it scrapes off

Sponge possibly? Are they soft?

Well coraline would be a good thing haha, especially compared to other things that are about there, I haven't checked if they are hard or soft, I will do that later after my tank wakes up. The tank is a month and a half old, probably is time for the coraline to be coming.

They more than doubled overnight they went from 2 spots to 5, I ran my mag float across them 2-3 times and they disappeared. Will see if more appear tomorrow
