Watch the feeding route
Fish may intercept pellets or flakes before they settle, leaving shrimp with less supplemental food. Shrimp can still graze on biofilm, but a crowded community tank changes how food is distributed.
Try placing a small serving near cover after lights dim, while still checking the next day for leftovers. A dish can help reveal whether shrimp reach the portion.
Do not overcompensate
Adding extra food to outpace fish can create waste and worsen water quality. Consider a species-only tank if the colony is not thriving alongside hungry tank mates.
Select food and feeding times that work for the whole aquarium, and monitor shrimp condition rather than assuming that disappearance means shrimp ate it.
For your own tank
Try placing a small portion in more than one protected spot and observe who reaches it. Do not increase the total amount unless shrimp are clearly underfed; leftover food can harm the same water quality the animals depend on. Consider whether tank mates are a good fit.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
