You might want to PM a moderator and have this thread moved to the general discussion area, where more will see it. But as I'm here, I will respond.


Yes, you have too many fish as they grow. Mollies get large, and need at least a 20g long tank, preferably larger. Lopng means 30 inch length, the standard 20g is 24 inches. Mollies should grow to 4-6 inches.

Mollies need moderately hard or harder water. Glowlights are the opposite, needing softer water, though they are somewhat adaptable but not to extreme hardness. Their pale colouration may be due to the water parameters. Do you know the GH, KH and pH of your tap water?

Glowlights would also be better with a larger group; if you can remove the mollies, you could get another 3-4 glowlights for a total of 7-8. That would ease their stress from too few of them; shoaling fish live in groups of hundreds and this impacts their physiology.
