Which nano for seahorses? Opinions needed ASAP

[Jesswalker]

Hi. I'm taking the plunge an buying my first marine tank. As I'm a newb I'm thinking an all in one would be better. I plan on 4 erectus seahorses and soft coral. Which tank is Breyer in your opinion?
1. Aquael reefmax 105 litre
2 Kent bio reef 94 litre
3 boyu Hs-60 128 litre
4 boyu hs-60 a 128 litre

I'm buying one tonight so any opinions would be great!!! Thanks

I'm not familiar with the tanks you list but keep in mind that seahorses need a taller tank rather than length or width.
