Hi Jools,Dukerider,
Just a passing thought, what's the difference between a dye injected cory and a dye injected zebra pl*co? Or a disco glass fish or red parrot c*****d? Would you complain about the former as energetically? Of course you would, I think?
In short, nothing. I don't see any difference between injecting dye in a zebra pleco, disco glass fish or any other fish. There's enough variation within the fish community to keep me entertained for far more years than I will ever be able to keep fish for....so I don't see any need to dye fish regardless of it's aesthetics or popularity.
The only reason I commented on the zebra's is I breed them, so I was naturally drawn to this thread rather than say a thread on dyed glass fish...but that doesn't mean I still don't feel the same way about them.
First and foremost, I have no problem with breeders crossing species for experimentation. I would not however, if I was in that position release them to the general public so for me that kills your question right there. As I said earlier I think there are plenty enough fish out there naturally to keep everyone interested without having to create new strains and variations.This is now getting a bit far fetched, but say, for arguments sake, some one "crossed" a zebra pl*co with a common and you got a colourful fish that was really hardy and laid 10,000 eggs at a time. Zebra pl*co market crashes, pressure on wild populations is eased?
Which is the greater good or evil?
In response to your question though...I'm not sure there's any scenario which I can think of which would result in a crash of the zebra pleco market. It's such a sought after fish that there will always be a higher demand than supply. Even if a new cross appeared on the market which matched your description, it may satisfy the average fish keeper, however there's enough purist fishkeepers out there to keep it in high demand for along time to come. The only thing which could help reduce the pressure on the zebra pleco is if other new just as striking pleco's where discovered, which would help spread the load as it were.
