This is one of six tanks that I have with built-in internal filtration units. I specified the design for these and had them built into the tank
at the time of manufacture. They are efficient and very low maintenance. They are also separated from the main tank, so large fish cannot
interfere with the filter in any way, and there is space to put a heater in the initial filter chamber too.
The tank itself is wide (front-to-back), but not very high - ideal for raising mainly bottom-dwelling predators which need plenty of floor space,
but in some cases need to be able to reach the surface easily to gulp air.
