Chris, what kind of fish did you want to keep? A lot of the african rootwood I've bought at least from aquatek hasn't leached many tannins into the water. Malaysian driftwood is a different story - over time it made my old planted tank look like iced tea. This isnt necessarily a bad thing as it will lower ph and soften the water somewhat and help produce suitable conditions for some black water fish.
Carbon will get some of it out - otherwise just leave it in a tub to soak in the backyard or such for a month or two changing the water periodically.
I have 2 freshwater tanks, one 30 long tanganikyan and one 60 cube west african riverine tank - unfortunately your two fish wouldn't fit in either set up or I'd give em a home.
30 Gallon reef, 220 gallon South American Cichlid tank.
