Thanks. I was nice to do it and see the results afterwards. The frame was made of Ytong blocks. The frame of my next tank with be made of stainless steel.
Here some pics of the fish i kept with my stingray's in past few years. At the moment i only got stingray's and a few Stendker Discus. the Discus i keep with my smaller ray's.
