Hi John, Toronto water is medium hard so both borelliis and endlers do fine. I wanted to know because there is someone who contacted me regarding obtaining apistos from me and she's keeping endlers livebearers. She says the they are more or less extinct in the wild, so I wouldn't mind keeping some as well. (Fish exchange program). G.
