hey everyone I am trying to get my wife into this fishkeepingthing a little to get her off my back and we found her a syno petricola today that she really likes. She was also eyeballing some julidochromis today as well. So i kind of got the idea to turn my 29 into a tanganyikan setup that she can choose the fish in. My first question is substrate. I kind of wanted to stay light in color to mimick their real habitat so I was eyeballing some salt water substrate called argamax sand from drs. foster and smith. Will this work for a tang setup or will there be water quality issues? after that I planned to stack some black slate I have to make caves and maybe ad a couple java ferns that I have growing. Will this setup work or am I heading for a disaster? thanks in advance
