Yeah after doing further research (Thanks to our lovely new reference library

) I read that the Niger's can be kind of hit and miss in terms of agression. Some can be big bullies, while others not so much...
I hate being in the situation of "do you chance it.. " I definitely don't want any agression going on with the clowns and other fish I currently have. But, having said that.. if he starts becoming a menace I can remove him and put him in my empty 20g ...
Decisions , decisions....
