neon goby pair

[justinl]

Right now i have one neon goby but i was thinking that seeing the interaction of a pair would be cool (like with clowns) so i thought i would go pick up two more neons (that would give me a fairly good chance of having a male and female right?)

so my question is that if two of them pair up, is the interaction interesting or am i wasting my time? also what do i do with the loner that doesn't pair up? will it get beat up on or should i remove it?
