Great looking tank and setup! From what I have read and seen it will suit Tropheus down to a tee! Also the colour of the rock is perfect. The one thing that I might add is that the blue background on the tank coupled with the white substrate will make the colouration of the fish seems washed out slightly. If it would be possible and not too much hassle I would recommend changing to a darker background to really show the fish off. All in all, a really nice sophisticated tank setup, keep up the good work and make sure to update!!
What is the ph of the water from your tap? and if it is low are you planning on using any particular buffer to bring it up? Also have you made any decisions on which spp of Tropheus you are thinking of keepinig?
