Ok originally when i saw my mollies at the surface "gasping for air" i panicked thinking they were dying but after monitoring their behavior I've realized they only do it when they see me walk up to the tank. Sooooooo i fed them and they gobbled it up and were back to swimming around. I'm pretty sure feeding twice a day is all that's recommended, but honestly i have to be over feeding them because i fed them 3 or 4 times a day. Am i not feeding enough during feedings or are these just some needy fish? I do 1 pinch for each fish. Should i just keep feeding until they stop eating and clean the rest, leave it at 2 feedings no matter how much they beg lol?
