Consider the species and tank conditions
Small snails are often kept with Neocaridina because they do not hunt healthy adult shrimp. Species differ in size, reproduction, and care needs, so identify the snail before adding it.
Both animals need compatible temperature and mineral conditions. A snail that struggles to build a shell may point to a broader water-chemistry issue worth testing.
Keep the population in balance
Snails may reproduce quickly when extra food is available. Feed the shrimp modestly, remove leftovers, and avoid adding more animals than the filtration can support.
Do not use snail-control chemicals in a shrimp aquarium unless the product is specifically confirmed safe for shrimp and used exactly as directed. Manual removal is often the safer first step.
For your own tank
Before combining species, verify the snail's adult size and likely reproduction rate. A few hitchhikers can become a large population when food is plentiful. Observe shell condition and check water minerals if snails or shrimp repeatedly show growth problems.
Use these as general hobby references. Test your aquarium and confirm product guidance before making changes.
