While I am home for the holidays, I went to my mother's kingergarten classroom and fixed up her 10 gallon fish tank. It was in desperate need of help; there were no decorations, only gravel! I got a large "grotto" decoration and a few plastic plants and it really improved the tank.
The tank has 1 black and brown pleco, about 5 inches, what looks to be a male guppy and female fancy-tail guppy, and some other small fish that I can't identify. It may be a type of tetra. It is about 1 inch long and has black and white horizontal stripes across the whole length of its body. Here is a picture of it (sorry it is blurry):
Does anyone know what type of fish this is?
