Just read this post - that's a great idea, a wall-tank! If only I had the obvious building skills you've got there - and a house, not a flat to modify, one day.
The equipment (from another post) looks impressive underneath. Thank for your journal, I'm learning tones off this site thanks to people who are taking the time to update with their trials and tribulations. From this I'm going to be adding one fish (unless pairs) per 2>4 weeks. Might take a while, but I'm too scared to do it any other way. That said, I've not got the tank ready yet, so the patience/waiting test/game hasn't really started yet! Like the acid etching too.
