Wow, maybe u should do a reef, or else Ill trade lights with you, lol. I have PC's That are perfect for a 75 (on a 55, but same length). Volitan lion will not outgrow a 75. I dont even think mine will outdo my 55. Becuz A.) I will have a very tough time letting him go and B.) he doesnt swim around much anyway. Volitans are totally cool, and look nicer than dwarfs, plus volitans are really hardy. I wouldn't do a trigger with a volitan, cuz it might attack it. Volitans are mellow to anything that wont fit in its mouth btw. They really cant attack, just swallow, lol. But, if they are attacked, in defense, they can sting their attacker. Tangs do very well with lions, but if an eel tries to bite at yer lion, good bye eel and lion. Maybe a SFE, they are mellwo enough, and if the volitan is large enough, it wont attack. Like Conogre says, Aggressive fish arent territorial, and they cant eat it, they will respect it, lol. TRy to talk to him, cuz he knows his ----. Hope I helped:cheer:
