I recently picked up a 33 gallon long, 48x12x12 and was wondering what anyone would recommend for it. It will be a planted tank and was thinking about doing a large school of tiger barbs but I already have a 20 gallon long with some corydoras and cardinal tetras. I was wondering if there was a singular or pair of fish that would fill the tank out or maybe something like a couple Pictus catfish any ideas are welcome
