Nope... nothing much at all. I have found this thread to be the most helpful so far
I am only new to large fish tanks (250ltr) and not really sure about anything. The only other fish tank I have had was a fighting fish in a goldfish bowl. I am going to take it slow and steady and try not to throw the balance of the tank. I will up the frequency of water changes, but not the size, as I have noticed this pearl gourami gets a little stressed when I have done larger water changes. I have 10 neon tetras, the pearl gourami, a blue gourami and a fighting fish. I have been told this is a strange combination, but it has been working so far with not too much aggression, except at feeding time, when the fighting fish rules the surface and tries to scare everyone away (he never succeeds though).
The other fish seem fine and apart from her eyes, the pearl Gourami appears okay as well. I have no idea what the problem is, but because the water is their lifeblood, I am going to try working on that
