I agree. there are a lot of CA and even some SA cichlids that have been found in brackish waters, sometimes even full salt. however I don't believe that they stay in those areas for extended periods of time. I think in most cases it's the cichlids being found in those areas looking for food. they are very tolerant and might be able to adapt to an unusually high salinity level, but I don't think it would be best for their health. there are no CA or SA cichlid species that are considered a "brackish species". a little bit of salt might be ok but actualy brackish conditions I think would be detrimental in the long run.
