The tank itself has settled down nicely. A bit of bogwood 'roof' became detached (OK I was clumsy during a water-change!) and is now floating around. It may or may not sink eventually but the moss and Bucep stapled to it are enjoying their drift around in the 'sunshine' for the time being at least.
Although the fish have access to both sides of the tank, they've all steadfastly remained in the left-hand side. For a few weeks I wasn't able to see them at all unless I dropped in some food and then quickly scootled away to a dark part of the room to observe. Over the past couple of weeks they've become much bolder and now actually come out of their cave to demand food if they see me. The following pic is (as usual) blurry but you get the idea :
Two of the new Eirmotus that I invited to join those already in the 400L tank have also shrugged off their shyness - at least I assume it's the same two each time I see them. There's a slight but noticeable size differential between them and those in the species tank, the latter not having to compete for food, of course.
