Just a thought: That setup will be a massive PIA to have to take apart to retrieve a dead fish or something at the bottom in one of the little caves they will create. I have learned to go a little simpler on the rock formation, maybe 3 separate "towers" so you may only have to take apart one at a time.
Your right for sure ironspider. Thanks for your input probably gonna let the tank sit how it is. Would kept it a little simpler but its gonna be in my living room hoping in the future to change the stones for better maneuverability. The stones you see i got for free from my neighbors leftover landscaping.
While I agree with ironspider about problems netting a dead fish and even more important is netting a sick fish...separate stacks are good. The first arrangement was better for mbuna...second stack does not go high enough.
I also like to avoid touching the glass with the stones...main problem is scraping algae off the glass where the stones touch. Secondary problem is stones can scratch the glass.
