So, about two weeks ago I set up a tank where I essentially scoop some water out of a pond near my house and poured it into an aquarium just to kind of see what happened. Most of the inhabitants are fairly standard fare for a pond: a few snails, some cyclopes, various small specks and water bugs, a couple worms. However, there is one organism that has me confused. Yesterday, I noticed a transparent blob on the side of the tank. I initially assumed it to be snail eggs, but I noticed today that it can crawl around, and quite quickly at that. The blob is a little under 1 cm in length and abut 2-3 mm wide. It is mostly just clear jelly, with two long structures being visible inside it, one orange, the other off white. Google searches have turned up nothing and I haven't any idea what it is. Any help would be appreciated.
