10 gallon RCS build

[DjPotter79]

This is what I want my stock to be.
RCS
A pair of cpo dwarf crayfish
And a school of pearl danios
But I'm starting from scratch and I need to get everything. I know I want black sand but what filter should I get and I want to get the best. Pleas let me know... Thanks

I think your crayfish would eat your fish. I think your fish would eat your shrimp.

Yeah and to add to what Lynda B said, I think the crayfish might eat the shrimp too. I've heard about it.

I've done some research and what I have read dwarf crayfish don't bother anything and I'm gonna have it pretty well planted.
What would be a filter for this tank?
