Black Phantom Tetras Acting Strange!

[xCowlesy]

Hii, i had 6 Black Phantom Tetras, but one died not so long back, (i think it was a female one, not sure).

Now the rest of the 5 that are in the tank are acting wierdly, they are just sitting inside the plants and only come out for food, they aren't energetic or happy like they used to be.

what do i do?!?

Big water change (warmed, dechlorinated water, of course) and see how they look then. Five isn't really a shoal, in fish terms, so you may need to think about adding some more.
