Live Scuds (Freshwater Amphipod) are highly recommended as a nutritious and easily cultivated live food source for predatory fish in home aquariums.
Freshwater Amphipods, also known as Scuds (Gammarus sp.), are a type of small, shrimp-like invertebrate found in many waterways across the globe. These organisms are native to both freshwater and brackish/marine environments and have a detritivore diet consisting mainly of decaying plant matter and scavenging.
In aquariums, Scuds make an excellent food source for micropredators, such as rasboras, loaches, cichlids, and livebearers, due to their rapid reproduction rate.
With just one starter culture, one can continuously produce a plentiful supply of live food by cultivating them in a separate tank where they won't be outnumbered by predators.
Live Scuds can be found in various habitats and may consume decaying plant matter and newly molted dwarf shrimp and their fry. Controlling their population can be achieved by culturing them in a separate aquarium at temperatures above 75° F (24° C).
One Culture portion is roughly 50x individuals at various sizes and sex.
