Even though the rock work is going to change, the cichlids seem to love it. Many times I have looked at the tank and they are swimming through the rocks. Going out of town tomorrow morning for a week, so I will let my friend watching the tank have fun getting them out of the overflows if they keep swimming into it. Planning to add 100-150 lbs more rock when I return (rock wall between the overflows), as well as add the Purigen that I ordered, and probably add ~5-10 more fish (depending on the ammonia and nitrate levels). I think I may also need to add a powerhead to create a little more water movement. Otherwise, off to a good start.
