Fish On Their Side

[Maxta]

Earlier we lost a gourami, hours later the other gourami is alive....but on its side, laying on the bottom of the tank.

Its still alive but on its side in a different location.

Now, our lone black molly is now on its side at the bottom of the tank.

This is my dads tank, not mine.


Any ideas?
