There is nothing decidable about Molly Fish Food. The mollies will eat many types of food, the typical flake foods available seem to be sufficient.
I’ve seldom seen a sailfin achieve more than 3.5″ length when they can reach 7” in the wild. This is probably due to their food sources being insufficient which is often due to the tanks they are kept in being too small. It is also perhaps due to a lack of a constant supply of insect larva that they get in the wild.
Tubifex worms, which are harvested live in the Delaware Bay, also seem sometimes to cause problems in a tank. I’ve had them establish colonies in the sand.
I don’t trust the supply of live food to be entirely free of parasites, which can afflict any tank kept species.
Do let’s come to the point about what they eat?
Molly fish food: What do they Eat?
As you Know that Molly is livebearer and omnivore by nature. So you can quickly estimate that what you should give them. They can get energy from animals and plants as well.
I give a treat to my mollies now and then by Giving them flakes.
