Nice set-up. Seems kind of crowded though. What does the filtration system/water change schedule look like on a tank like that. I haven't had a tank since I was a teenager but am thinking of setting something up that would have qualified as a dream tank back then. I live in northern Costa Rica right now and if I make the choice to make it permanent, I want to build a large "native" tank behind my house with fish caught here on my property. There are a lot of different cichlids, one that I especially want to try and keep gets about 18" long and has gorgeous blue-green markings. No idea what it's called in English, they call it "guapote" here, but that seems to be a blanket term for large cichlids. Anyways, I just found this site and figure I'll pick the brains of anyone who'll let me.
