interesting fish

hi people this is my first post mostly just to say hi but i like oddballs and raritys but i managed to get hold of a few things lately, i got hold of some acnodon normanis there very small at the moment and very cute, but ive read they get 4-6 inches long is that right and also mine quarrel alot yet baench says they are schoolers, does anyone know any different?
Also i looked at a wholesale list and saw fresh water lionfish i thought it was the robustus but it doesnt look like it, it looks more like a stone fish, are there more then one type of freshwater lionfish?
thanks Danny
