Arcadia Arc Tank 35 litres Shrimp Question

Ok I have spotted another option for a shrimp tank, Just want some peoples opinions on using these tanks for breeding and keeping CRS and RCS, are they adequate or too small?

Would a simple sponge filter be good enough for these tanks or would an external canister be a better option?
I will have cash to buy a new Aquarium setup this Monday coming but I'm finding it difficult to choose a tank, Ive narrowed it down to either a Fluval Osaka 155ltr, two Fluval EBI tanks or two of these Arcadia Tanks, what would you choose?

Dimentions: 28x40x33cm (WxLxH)
