Blastos forming bubble?

I don't have a pic because it's really hard to tell due to the "fluffiness" of them but my red blastos are overgrowing the rock they are on and as a result keep pushing outwards basically. Last time they just grew a tumor looking on the side and I fragged some off for Cammie, this time around it looked like a sponge was growing under them but I cut into them and it was just an air bubble. The weird thing is I've had them on the rockwork forever and they never grow onto it, just cover the rock they are on more, maybe I need some epoxy. Anyways, who wants a blasto frag? 1st to respond can have it, although it may be a month or two before I make it to a meeting. That'll give it time to grow out too.

well tiff I'll respond first, and will take one, every thing i have gotten from you has been super nice. what color is that 1 ?

These guys, I'll put you down for the frag
