About a week a go I went to the pet store and bought 5 skirt tetras. This was a newly set up 20 gallon tank (they are the only ones) so I was going to let them help out in setting up some bacteria for the filter. They all started out pretty happy and enjoying swimming in the tank. Now though about 2 days ago they all started hiding in the fake log. I don't know what started there hiding trip or how to get them out.
Please help.
P.S. They come out to eat then go hide again
