Does that mean you have 2 filters, 1 eheim canister and 1 internal filter?
There's also cave/tube thingy there.
I'm saying it is the case for your tank, but introducing multiple things can cause parameter change and/or chemical discharge. Even for rocks, if not chosen correctly, it will increase certain parameters over a period of time.
From what I've seen, most people have simple setup when it comes to shrimp-only tank. If you are restarting the tank, probably you might want to consider making it simpler, just substrate and plants. Those standard equipment is still a must (eg filter) but that additional internal filter is something to reconsider.
Afterall it will also such the shrimplets in.
Yes, as Zac mentioned, the tetra will be snacking on your shrimps.
