Shirakura, Mosura, ADA Red Bee for CRS and EbitaBreed Spinach.
The best shrimp magnets are: Shirakura Specialy, Ebitabreed Spinach. Probably because of their ingredients, flavour.
For small shrimps we just brake these pellets to smaller pieces. For tanks where we have giant amanos too we throw in the largest pellets so they can't fly with it 😉
For baby shrimps Shirakura Chi Ebi and Mosura BioPlus. The Mosura one is a great one shrink immediatelly and works also great as a shrimp magnet for baby shrimps.
Catappa is also used. And some species there's the algae in the tank. Like Tigers, Black Tigers. 🙂
