Hi. We have 4 platies, 4 danios and 3 corydoras. We know the platies are brackish and the others aren't. Will the corys be hurt by the salt if we add it? Thanks in advance.

The simple answer is yes, long term exsposure to the salt will kill the cories, however, platies can be kept succesfully (and bred) in completely freshwater :)

As Oddball said...Corys and salt do not mix. :S

Thanks very much.
