Sounds like one sweet *** tank I must say but must warn you on the arius seemani. They get huge fast and make a huge mess of walls and the floor. I had a school of 4 in a 90 gallon and they are just so active and destructive. They grew from 2" to 10+ within the first year with the big female 12"+. They constantly brought the tank down 2" a day from splashing salt water all over my walls and floors, also got my tv once. The other problem is their appetite. Costs a lot to keep these guys fed. Were fine up to 7" then they started eating my archers, as well as a few small scats. I absolutely love these fish but are a huge headache. Try em out, but I see you getting rid of them within a year or so. Add some strong power heads as they love the flow and will swim at it in one direction almost all day except for feeding time. Best of luck with the tank and let us know how it works out.
