Yes they did come from different sources. Like I said before, the first batch of 6 came from J. Rapps and all have perrished one by one over a course of a few months. I doubt that it was a matter of unhealthy stock or poor maintenance prior to me owning them. The other specimen was purchased as a tiny fry from a local store. He lasted about a year or so growing from less than an inch to about 4" or so.
Actually looking at your fish, I am drolling here and can't help but to think of trying it again
