Females grow noticeably bigger and consume much more food than males. Live food makes up a large portion of the diet for Least Killifish. Here you can see the large female is hunting on scuds. Toothless least killifish are relentless hunters, always looking for sizable, live food to swallow. I populate my aquariums with scuds (scientific name Gammarus). Adult scuds growing up to 1 cm long are too large for least killifish to swallow. Scuds live up to one year, breeding proficiently in aquariums. Mature adult scuds deliver a batch of new babies every month. Least Killifish feeds on small-sized baby scuds. 01:11 Some baby scuds survive and grow large enough to be safe from least killifish. I replenish the population of scuds in my aquariums on a regular basis. For this purpose, I farm scuds in a separate fish tank without fish in it. There are different ways of harvesting scuds - check my previous videos for more info. In this example, I use a turkey baster. Simply drop scuds in the aquarium with fish. I do it once a month. Adding different size/age scuds into an aquarium is the same as seeding a new culture. This way, fish have plenty of baby scads to hunt the whole month and even longer. Scuds feed on plants and whatever organic waste is available and continuously breed right in the aquarium. I also feed Least Killifish with other food 3 times a week. Least Killifish in aquariums with a strong population of scuds can be left for up to one month without additional feeding in my experience. Have fun and happy aquariums :)
