I have a 55 gallon that is currently up and running, and finally settling down after some wild spikes in the waste cycle (Accidental dump of food in the tank that was not cleaned up while I was out of town).
I am considering putting in a small colony of Thorichthys meeki (Firemouth Cichlid), and my experience with cichlids tells me that they will most likely breed at some point.
If I am intending on returning these fish to the commercial cycle (i.e. there is a local store that purchases fry for resale), should I worry about getting the fish from different sources? I'm only concerned that if I get them from the same source at the same time, I run a greater chance of them being from the same batch of fry, and raising the potential for inbreeding.
