What to feed gammarus?
You can feed your gammarus any kind of invert-friendly food, including blenched vegetables and kitchen scraps, fish food pellets, dry leaves and algae. In nature, amphipoda are detrivores and scavengers, so they are pretty good at finding food from their environment – even if you forget to feed them for a couple of days, they will likely be fine as long as there’s enough decaying organic matter in your tank. It is better to avoid overfeeding them fish food containing copper as this mineral is toxic to inverts in large quantities.

Can you keep scud shrimp in a tank?
Scud shrimp can be kept in communal tanks but you may encounter issues in which they are competing for resources or being preyed upon by larger fish. If kept in an aquarium with shrimp, gammarus tends to reproduce at a higher rate potentially causing an infestation, and overfeeding on vegetation. There have also been reports of gammarus preying on shrimp fry, so it may be best to keep scuds and shrimp in separate tanks. Keeping freshwater isopods and amphipods together may be more successful as both species are highly prolific yet require low maintainance, and are unlikely to prey on each other. Scuds and freshwater snails are also generally safe to keep in the same tank, and they both make a great addition to a self-sustained planted ecosystem or jarrarium.
