i have more than 1, i cant keep more than 1 per tank and im out of tanks at the moment. im in no rush to sell, the bigger they get, the more ill get for it. these guys will fight each other why i have them separated. as you can see this guy is healthy, so is my other one. plus im in the process of picking up a couple of mangrove jacks i want to fully convert and mix in with this mix. keeping these fishes isnt for the noobs. at 140 full fresh thats still cheap. then again you need to know how to keep these guys survived. i did my part in converting them full fresh, its up to you to do your homework and read online on how others kept theirs in full fresh for long periods of time. bump
