I agree, although you can try with antibiotics or epsom salts to draw out fluid out of the fish, but most likely the molly is not going to survive this, but you always can try.
I agree with the others. Did you use something like Tetra SafeStart Plus to jump start your tank. If not it usually takes around 6 weeks to cycle a tank. Do you know about the nitrogen cycle? Do you have a water test kit to test for ammonia? Sorry for all the questions but they are important and I do not want to see you lose any more fish.
That’s ok, I appreciate your help and don’t want to lose anymore fish eitherSorry about your fish
I used Tetra SafeStart yes, I also have the Tetra test kit that shows nitrate is 25ppm and nitrite is 0. Everything seems to display as ok when I do a test, apart from the water hardness is a little high.
I do not, the testing kit I have doesn’t include ammonia on there. I will visit the fish store near me to pick up a testing kit for that now and will let you know!
You've got the perfect hardness and pH for mollies, but I'd say the tank is too small for them and bit too much livebearers stocked in it. Mollies need a 30 gallon tank, a 30 gallon tank would be fine for 4 mollies.
