Freshwater/Brackish Compatibility Chart

I was looking at fish that may be compatible with the ones I have now, when I came accross this chart that seems real nifty. I didn't know until a few days ago that angel fish are somewhat aggressive, and can maybe fit in with my chilids and sharks. Here's the link to the chart.

I've seen that chart before and not posted the link here because it is too general, which makes it very misleading in some cases. Yours is a good example. No freshwater sharks exist and even most of the smaller fish that are called sharks are not compatible with angelfish because they nip fins. They might be OK with very peaceful freshwater "sharks" that don't nip fins, which most sharks do. Your Colombian sharks are brackish water fish and will not do well with freshwater fish. Plus they are predatory and will probably kill anything smaller than they are. Remember, they will be a foot or longer when they mature and will not survive in freshwater. It's only when they're young that freshwater is OK for them. I don't know which "sharks" that chart means, but please note that even with that non-specific, misleading title, they only give a cautionary recommendation for freshwater "sharks," and say "no" to brackish water fish being combined with angels. I would always get second and third opinions before taking recommendations from that chart.
