Okay, so I'm starting out with a 90 and other than the bitty clown loaches I'm pretty well stocked. I have a jack Dempsey, a green texas, six silver dollars, and five clown loaches. I realize the loaches are going to outgrow this and I haven't decided if I am going to keep them long-term yet. How big of a tank would I want for the five clowns if I wanted a cichlid community in the upper levels if I decide to keep them long-term. Note that I don't have any plans to add any more fish to the 90, I mostly just want to let my fish grow out.
