The back ground is made of poly covered in sand and coloured cement then painted with resin it's different shades of grey when not covered in algee.
There are tropheus, leleupi, transcriptus and bn's in there. There is also a cory sterbai and a herlequin which I used to help mature the tank before I put the rest in, I presumed they would not last but are both still going strong, look a little out of place but are ignored by the africans.
