yeah a 120 would be fine for polys if the clown loaches were big enough then you could keep polys with them
Dats would out grow the tank eventually but grow pretty slow like clown loaches so if you got small dats they could work with clown loaches if they were big enough at least for a while
I have loaches with polys. I guess it depends on what polys you're getting because if you get lower jaw which will grow bigger than upper jaws then they are very capable of eating loaches.
