That is a 1250 litre tank. I put in 800 litres of old water, a "ton" of cycled material, and in they went, my 4 Silvers and 3 Blacks. Also two small knives and a pleco will, eventually, find their way into the tank.
I will see what gives..this is a "benchmark" experiment to be followed in "real time" ( as the business guys speak ).. I have a lot of space left over in the other tanks to solve any issue that may arise.
What I like most about this tank is it's 80 cm's width . It makes the diference, both for the aros as aesthetically, imo.
