Antennata Tank Size?


New member
I have a just finished cycling 50g tank and am interested in essentially turning it into a predator only tank. I want some sort of lion and was wondering if it was too small for an antennata. If I did get a small one, how long would it take it to outgrow the tank?
If the tank is too small I have no problem moving to a dwarf of some sort, I just love the antennatas and was wondering if I could keep one of them instead. And yes, he would be alone if it was the antennata. A dwarf might have some cellmates if I go that route though.
