I've kept a couple, very hard biters, very sharp. I sent my other laptop in for repairs so I'll have to find my backup disk and put some pics up, but they are a very beautiful, personable species.
excellent fish to own, mines roughly 6" now and the most interactive and aggresive fish i have. 75g is going to be too small for life, a 120g is bare minimum, and you need a ton of filtration, these things are like aquatic pigs!
yea...they are great fishes to own...and have very nice personality...=) i have one and a video of him eating a live crab with true aggression....like he goes crazy with it...lol i get it up and posted
here's the video but you have to skip most of the video to 5:00 in the video to see him feeding on the crab....or you can just watch the whole 6: something minutes...but its quicker to skip... enjoy lol
