I bought this for my dad as a birthday gift, I hadn't been interested in the fish until a few weeks ago when I noticed the pregnant molly. Been doing some research since, and learned that the gender balance is way off(3female/5male). I was thinking this might have something to do with it.
The tank is 110 litre it contains the 2 molly fry, 8 molly, a small red tail shark, a yoyo loach and these these 2 little fish I cant find the name of.
Im using a test strip for this - PH 7.2, KH
I think one of the other mollies is pregnant too, looking a little chubby, not as big as the other one though.
