Lucky number 5. For some reason I always buy my cichla in fives.
Depending on what size your "grow" out tank is and how big the baby bass is then go from there. Two bass would work as baby bass, But (IMO/IME) they tend to form a school (5+) when they are small and they teach each other to eat (Pellets, shrimp, crickets and so on). To answer your question, I'd say get two.
Subliminal messages. Gotta stick to the roots.
Hawaii Five-0..book'um Danno
Right.and 2 wouldnt compete to the point of killing the other or anything like that, right?
Right.
Two is better then one, But you could also add dither to train the bass to eat to. Giant Danio's, tiger barbs, blood parrots...things of that sort.
Single one would hide.
