What a dish changes
A feeding dish keeps sinking pellets or vegetables in a defined area. It can make it easier to see what remains and to remove scraps without searching through moss.
Shrimp may take time to discover a new dish. Keep it near a familiar grazing route and avoid placing it where strong current blows food away.
Keep it clean and simple
Rinse the dish during routine maintenance and remove food before it breaks down. Glass or aquarium-safe ceramic is easy to inspect.
A feeding dish does not make overfeeding safe. Continue to size portions to the colony and check whether food disappears in a reasonable window.
For your own tank
Choose a dish with a shallow edge that shrimp can reach and that does not trap waste underneath. Place it where you can retrieve it without moving hardscape. If the dish makes food harder to inspect, return to a simple open feeding spot.
