The tank isn't much to look at to be honest. It's a 450L 4'x2'x2' with rather gloomy lighting and a bad case of algae!
Here are a few photos I've taken this evening showing a bit of a wider view and some of the tankmates:
I'd just been doing a bit of siphoning and had kicked up a load of gunk - should have taken the pics first! Schoolboy error...
Tankmates are a school of Congo tetra, an SAE, 8 Brochis splendens, a few Otos, and a pair of Farlowella vittata that breed occasionally (I have another tank full of their kids and grandkids)
