idea for the 40 gal

I have been wanting an amphibian tank for a while. Right now I am setting up my simple ten gallon planted tank for three ADF but down the road after my ancient kissing gourami has passed would it be ok to divide the 40 long tank down the middle and put an axolotl on one side and two ACF on the other? They have the same temperature requirements and filtration needs Other than the ACF not liking vibration but the tank will have 80 gal of filtration on it. Just wondering if i should even consider this idea. They are both very sensitive to water quality so the water would have to be pristine. Also I Love watching my Gourami and he's doing great its just every time i look at that tank I think about converting it lol. I've looked at the needs and feeding of each and down the road i'd love it. And I promise this isnt an ask and go do it in spite of what people say. if need be i will set up the forty for the ACF and a seperate tank for the axolotl I just though this idea would be cool

decided to make the forty a species tank and get one or 2 30 gals for other species tanks
