I never mix south and africans. I know it can be done, but just because you hear a few good stories imagine all the bad things that some people dont talk about. Or worse, have to pick between which fish to keep when it doesn't work out. I hate it when people bring in south Americans because they were picking on my other fish or worse... my geo died because my aggressive africans ganged up on him. Can I get a bigger geo or an oscar this time... i want to slap those people... stupid laws... and my need for the discount... being a poor teacher
