I just feel bad for the glowlights because they are sterile

Only 90% of them...
The scientist couldn't get a 100% target rate.

Did you watch the Movie Jurassic Park?? ;-))


They'll get into the wild eventually.
You can bet your last dollar on it that some twit will release them
into a river.

I feel that if we start buying these little monsters, what's to stop
them GM'ing another bigger fish or even another bigger pet?

On the 'its not caused any suffering angle'. I wonder how many
genetically deformed fry the scientist made before he got fish that
were just what he wanted. A few thousand?

Is exposing a fish to only UV light even natural?

Things to think about surely.
