IS a fluval 101 overkill for a 20gal long tank?


I want to set up a shrimp only tank, with different kind of species from ghosts to cherries etc and I was thinking of getting a fluval 101 canister filter.
The only reason I would prefer a canister is that that way the tank can be closer to the wall and take less space in the room.

I am looking at getting a 20" long tank, 30*12*12.
It will also have some low light plants, like jave ferns, no co2, and problably just a 20w lightbulb or something.
Basically growing plants is not the main objective.

My only concern with thefilter is if it isnt overkill for such tank?
Will it create too much current in the tank?

Do the shrimp prefer a strong current of water or a more calm one?

Anyway please feel free to sugest any other kind of filters.

I use fluval 104s on my 15 gallon tanks. The current doesn't seem excessive. I don't have the background to comment on how it will do with shrimp. It seems like babies would get through the intake strainer, so you'd probably want some sort of prefilter.

Have you considered a sponge filter? You won't have to worry about things hanging over the back of the tank or shrimplets getting sucked up.

I am using this filter on my 20Tall and it is fine. I put a sponge over the intake to keep baby shrimps from getting sucked up. All i did was drill a few more holes in the spray bar to lessen the force of the water coming out. You will find a few shrimp in the canister when you clean it but they are usually fine.

I use a Eheim 2213 Classic canister on my 20 gallon long with shrimp. The babies can get sucked up if I don't have a sponge over it, but that is true of any canister filter. The flow is plenty, but not too much at all. It is rated at 116 gph flow rate, but I don't know how that compares with the one you want to use. If the flow is too much, there are always ways to reduce the flow, but its not easy to increase it.
