Dear forum, I am planning to hack my wall and build a fishtank within it for my new 5 room hdb flat. Such that can see fish from both the livingroom and kitchen. I approached a few interior designers, they not very confident in doing it. I was wondering if anyone has done a fish tank that is in built within the wall who would not mind sharing their contact. It would requre the wall thickeness to be extended, piping for marine equipment etc. I looking for someone who can do the whole works for me at a reasonable cost. Thanks in advance
