This is Always going to be a touchy subject, specially with the fish Hristo owns, which are mostly Parrots, goldfish and discus, all being hybrid versions of fish in nature.
My personal opinion and one that I try to foster here, is that we should not NECESSARILY be political about this aspect of the hobby, we are here to discuss photography. I have gone towards both spectrums of this discussion, having started with breeding Flowerhorns and, since then, having gone away from any types of hybrid fish, as a personal choice. But I dont think it's necessary to discuss these opinions here.
On the other hand, Everyone's opinion is valuable whatever it is. Everyone is free to voice their opinion, as long as it does not PERSONALLY offend the person its targeting. Andreas' comment is general and is meant as such.
Play nice guys
Hristo, to get back to the subject, I am truely amazed by the improvement you continue to show. Those photos are wonderful and show what you are trying to convey VERY WELL. (notice I have said nothing on the subjects, I will keep my opinion to myself)
