Hey. Well here is my experience with these guys. They are beautiful, but beauty comes with a price especially as it grows. IMO they should only be kept by P. aquariums or by true aquarists. I had one years ago that was in the 4'+ range and was kept in something like 200 or so. We had to keep cinder blocks on top of the tank to atleast try and keep him in. Doing tank maitence, i.e algae scrubbing, was next to impossible. Tankmates, except for some damsels was not going to happen. One of the most aggressive and realistically dangerous fish I have ever dealt with. Getting bit will most likely cause a ton of stiches, worse the infection that most likely follow from the bacteria in their mouth can cause severe long term pain. I would go a different route. Most people think I am crazy, but if the Tessy does well and grows well, which they can grow at an alarming rate, it is similar to keeping a 6' saltwater croc. I am not kidding. T
