No I didn't . The knifefish I bought from them had some sort of disease even though they said that it had been at the store for months and had been quarentined , and so I had to treat all of my fish, and to top it off I lost $30 in fish. I swear that that store is the only one I lose multiple fish from . They said that they keeep all of their fish at 7.4 so I think thats why because most of my tanks are acidic. One day I will get a black though, but not from them
