Its like if you are in outspace and you are expose to the atmosphere. That is what the fish felt, gills strives for water to get oxygen. Too much exposure to air is a torture.
welp fishes can breath outside water, haven't you seen plecos surviving for years outside the water? just with rain drop, also fishes in tanks need to take oxygen from the top out of the water... Nonetheless they are gorgeous
Place the fighter molly in separate tank.... Then he will realize that he was doing wrong with other mollies................... And will not repeat his mistake again...
@Zere Chubayeva are you sure your aggressive Molly is a female? And what are the genders of the other ones? If the aggression still continues, try to add more plant cover and hiding spots into the tank. And if all of the other mollies are also females, this may be a normal hierarchy thing that some fish may establish amongst themselves. Try to get one male and two females the next time you buy mollies (or any other livebearer for that matter)
You can find most of em in your local fish stores (they're pretty common) and if you're really impatient about waiting for them to re-stock, you can try some websites like living artwork for example. They will most likely help you out!
