After a lot of consideration and thinking, it is finally time to upgrade the loaches to a larger tank

I started off with a few (6 of each) Botia almorhae and Botia kubotai last year in a 75g, which has now increased to a 120g. This year when picking up fish food I came across Botia dario unfortunatly there was only one in the tank and pity ended up getting her'him and was assured that there would be more in the following weeks.. there wasn't, the same happened with Botia striata. Basically I have now found a store that has these fish in stock and want to have numbers up to at leasst 6 of each species. We were thinking a tank 6x2x2 (with a 30-45g slump) but I just wanted to make sure if this left enough room for teritories and such like although all the loaches get on very well or would it be possible to have more than 6 of each species?
Oh and heres some pictures of a few of the loaches
