SW:
If you were to go down that track - alter a gene that produces venom - and you were breeding venomless RBBs, then what happens to it if one escapes? It won't survive in the wild without venom.

Incidentally - and I haven't looked at the genetics of venom production - but it wouldn't surprise me if there are several genes that produce the various toxins that comprise venom. There may also be inhibitors in the venom, and destroying those might make them more venomous.

All hypothetical, just me thinking out loud.
