Strange Water Bug
In October of 2006 I started an small enclosed microecosystem with a fish, snails, and plants. It all lived until recently, however, a new bug has popped up inside and the container has never been opened. He is very skinny, with about 10 body segments, a tail that looks like three small feathers, what I believe to be antennea, and is tan in color. He has been growing and likes to stay at the bottom of the container on the rocks or in the plants. What is he???? A new type of bug? Thanks!!!
p.s. I attached the best pictures I could get in the water.
This is a Damselfly Naiad. It will become a winged adult. Damselfly Naiads are often introduced into aquaria on water plants. The three feathered “tail” are the gills.
