I too am new to AGA and planted aquariums and am glad to see this list active. Rather than tell my story of my own rapid descent into the depths of Aquariholism, I'll get straight to my current question for the group. I have a newly setup tank that I noticed something floating in shortly after adding some new plants. I have to admit that since I didn't really rinse the plants off well, I don't know if it came from the new plants or was already there from some previous plantings, but here's what it looks like. It is spherical and about the size of a small marble in diameter. It has a center core that looks somewhat fibrous with very thin white hair-like threads extending outwards. The core is a darker opaque sort of ivory color. Imagine if you clipped off the head of a dandelion seed pod before any of the tiny seeds had a chance to blow away and this is what this looks like. Any ideas? It definitely seems to be vegetable in nature but I am very curious as to what it is. If it is a seed of some sort, should I put it back in the tank? Thanks in advance. ------------------ To unsubscribe from this list, please send mail to majordomo@thekrib.com with "Unsubscribe aga-member" in the body of the message.
