The body of Gammarus is laterally compressed and consists of a cephalothorax (head/thorax), seven free thoracic segments, a six-segmented abdomen, and a small tail (telson). They have seven pairs of thoracic legs, some of which are adapted for swimming and some for walking.

Why do scuds swim on their sides?
Because of their flattened body shape, scuds move around on their sides by flexing and wriggling. Amphipods, like crayfish, crabs, shrimps, and sowbugs, are crustaceans. This picture of a scud shows several of an amphipod's body parts.
How do you raise Gammarus?
For a successful Gammarus Shrimp culture, it is crucial to provide a dark aerated environment. Raising the scuds in such environment can be achieved by either providing a water flow or shallow water with a large surface area. Their diet varies widely as they are omnivorous feeders and are not very picky eaters.
What are aquatic scuds?
Scuds are members of a bottom dwelling class of crustaceans called Malacostraca. This class also includes aquatic sow bugs (Isopoda), crayfish, and shrimps (Decapoda). Although most scuds live in the ocean, over 100 species are found in freshwater. Scuds range from 5-20mm long.
How fast do scuds breed?
According to Morgan, a female that produces 22 eggs each 11 days potentially has 24,221 offspring in a year (but egg mortality is high). Scuds are listed as detritivores, which means that they eat detritus—fragments of decaying organic stuff—from the water around them.
How do you breed Gammarus shrimp?
The life cycle of Gammarus pulex is complex. Males grab and hold females before deciding which one is likely to produce lots of eggs. Then the male carries his chosen female for several weeks until she sheds her skin and the male can mate with her.
Do scuds need aeration?
Scuds are drop-dead easy for us to culture. ... We don't use as high a water flow as we do with our fish because scuds don't require as much oxygen as fish, so the continuous water drip provides adequate aeration. Scuds eat most anything, but we have an abundance of hornwort which they seem to relish.
Do scuds lay eggs?
Scuds do not really progress through stages. The females lay their eggs by releasing their egg pouch, and when the offspring hatch, they closely resemble adults (but are extremely small). A single pair of scuds may produce 20 000 offspring in one year.
How big do scuds get?
Size: Body length of scuds ranges from 5 mm to 20 mm (without antennae).
Can scuds live with shrimp?
I introduced some new Taiwan Painted Fire Reds in to my current TPFR tank and noticed a few scuds that came with them. I threw the scuds in with the shrimp. I don't see any harm in having them besides multiplying fast.
Are scuds shredders?
Scud (Order Amphipoda; also called sideswimmers and amphipods)- Shredders who eat mostly detritus, algae, bacteria, and any recently dead organisms.
Do bettas eat scuds?
They make excellent food for your bettas. The bettas will eat the smaller ones first and the largest breeders will be the last to go, which enable the scuds to reproduce in their tank. ... One wafer to about 250 scuds should last 2-days.
