Flathead Gudgeons (Philypnodon grandiceps), Freshwater Shrimp (Paratya australiensis) and Daphnia. The Gudgeons show some variation in colour – some changed to lighter shades after capture. The Shrimp also show variation in colour – the greener one and the blackish one are uncommon. The Daphnia are a very good size and would make good live food for a number of aquatic animals.
