Started this hobby in 1996 with a small 2ft tank converted from fresh water...
2nd, 3rd and 4th tanks were all 4 x 2 x 2.5H... with the 4th tank decommissioned in December 2022 due to moving house.
And finally doing up my last marine tank, which is a 5 x 2H x 2.5W with front and 1 side crystal glass
