I'm conjuring up an idea to keep 6 distinct-looking species of peacock bass together in a "big" aquarium. The fish I'm looking at are C. intermedia, C. kelberi, C. monoculus, C. orinocsis, C. piquiti and C. temensis with one good specimen of each species. Max size on these fish range from about 20 - 38" on FishBase, but I imagine that's in the wild. I've read on here that they get much smaller kept in an aquarium. What's your experience with max size ranges when raised in the aquarium?
