what is it that you want to achieve?
MTS are carniverous... they wont eat algae

Amanos will eat the fishes food rather than algae whenever they get the chance.
Not true.!!!!!!!
MTS
DO eat alage, they may also eat fish food.
Amano shrimps,
DO also eat algae, they do refuse some types of algae but will eat most. They will also eat fish food.
If your water is good enough for shrimp,Ie, low in heavy metals etc. I would go for some cherry shrimp and cardinia (mettitarter "spelling"? )
Along side them I see no harm with addnig MTS as well.
Heres a some links for where you may get snails and shrimp.
