As a few of you know, I had a fantastic opportunity come my way about 2 months ago. A very wealthy lady I know bought a home with an Oceanic 100 gallon reef tank with stand, canopy, sump, trickle filter...the works. She didn't want it, and basically said to me if you want it, come take it. So, after moving that incredibly heavy setup, and deciding what to do with my cichlids that I already had in my 55 (I was debating salt/fresh), I finally decided to just move my cichilds into a much larger home and voila: Now I know some malawi/mbuna purists will complain because it's not a "correct" mbuna tank...i.e., sand and rocks. I know this, I just don't care. I like the look I have now, and these same fish have had this setup (fake plants 'cause they'll eat and dig up real ones, and black gravel instead of sand) for the last 3 years and seem to be fine. Only problem is with a trickle filter, I need to stay on top of water changes to keep nitrate levels in check. Otherwise I've seen that they start to get much duller in color. Also been using regular ol' tap water for the same 3 years and it has not been a problem. Whadda ya'll think?
