Mines not quite as good, but hoping to get there soon
Currently got 2 small setups with my collection split, untill I find a tank big enough to grow them up in. Looking for 6x2x2 or similar with a 2.5 footprint similar to yours Simon. Had one a couple of weeks ago that fell through, and not found the right one again yet, not gonna rush into it though.
The above 6ft tank is going to serve as a grow on tank for most of these fish, with a few, who aren't quite large enough for the big tank, becoming lifelong residents. The new tank is a design I will start work on soon, but will be around 9x3x3 - 12x4x3, depends on space. It will be within this range I think, and will be incorporated into us buying the next house, with a room specifically for this (Yes I have a very understanding young lady)
Currently;
2.5x2x2 - 62 gallon
3 x Pictus Cats (Will be Living in the 6ft for good)
1x Banded Knifefish (Undecided on this or the BGK for the big one. Depends if I want anymore Knives in it. The other is in the 6ft)
1x Lima Shvelnose (for the big tank)
1x Palmas Bichir (for the big tank)
1x Ornate Bichir (Big tank)
1x Thin Bar Dat (Big tank)
1x Silver Dat (Big tank)
1x Fire Eel (Big tank)
1x RTBS (6ft, poss stay in this)
Also a 2x2x2 roughly 50 Gallons
1x Datnoid Microlepis (Big Tank)
1x Blood Parrot (6ft)
3x Senegal Bichir (6ft probably)
2x Armoured Bichir (Big Tank)
1x Striped Gar (Big tank)
1x Hoplo (6ft, hoping to add a few more)
1x BGK (same as Banded)
As you can see, heavily overstocked. This is very short term though, and would have been rectified but for a tank breaking. Will soon add the 6ft and then after about a year, the really big one will begin.
