Hate to be the one to tell you this, but bocourti get HUGE, and they grow fast... kinda like oscars.TheDangerZone;5051546; said:these fish looks pretty awesome, hope they do ok in a 50gal tank.
Your definitely gonna need a tank bigger than 50 gallons... I'd say maybe 90 minimum, though you ask me, I wouldn't put them in anything smaller than a 125 myself.
