I hope this works, I have items in my BioCube29, this tank is in it's 3rd week of cycling, the Ammonia is down to almost nothing as are the Nitrite levels. The worm looking things are roughly 3 inches in length. The picture UKNOWN1 is approx 1 1/2 inch sticking out on my LR with a velvet type texture. Can you help me identify these items?
