Minimum tank size for Sebae Monos?

[Dats.]

Whats the minimum tank size for say 3-4 Sebae Monos?

They get big. from what I have read, something like 6 inches when captive and 18 in the wild. You will need a rather large tank. I have three in my 120, but they are still little.

a 55GAL would be fine with 3 but if you wanna add other fish i say 70GAL - 90GAL
