how is grand sumo red for the long run how did it turn out for you and did u notice anything of i noticed that the fish got more aggresive and bigger i been only feeding for about to months
There are a few theories goes that GSR brings out color that isn't natural. But ask yourself why wouldn't it be natural? If the color is there then it should show, period.
I was in Singapore two weeks ago to attend the Discus Judging course of Discus Club (Singapore) and for the Aquarama Fair. There were some heavily colour enhanced fish competing in the Show. All of them made it to the first three in their classes. Some of the fish were hormone fed and some were colour enhancer fed. After the competition, I had the opportunity to discuss this subject with Dr. Sun, Andrew Soh, Colin Hang, Brandon Wu and Ivan Seah. All of them agreed that excessive amount of colour enhancers and hormone should not be fed to the fish BUT, they all believe that both colour enhancers and hormones CAN be used to reveal the real colour potential of the fish. Of course, nobody can really tell to which extend. We all agreed that the fish should not be coloured to the point where it looks artificial. However, some fish who got rewards on the Aqurama Show were so much enhanced that they were looking like they were made of plastic, including the Grand Champion. I talked to the owner of the fish Raymond and he told that he was using only natural ingredients in fish food to show the colour but even the fins were yellow which is a good indicator of heavily used articial colour enhancers.
This brings us to the point whether natural colour enhancers maybe used and artificial ones should not be used. I believe this should be the case. I don't believe that feeding paprika or spiriluna gives any harm to discus. However, it is not the case with artificial ones. All the articial enhancers which are beinig used on fish today were fist developed to be used on cage birds, especially canaries. Experiments made on canaries which were fed canthaxanthin in excessive amount showed that it causes liver and retina damage. On the bird products there is a warning on the label about this. However, most of the fish owners/breeders is unaware of this fact.
RD.;4587620; said:Not exactly. In some fish foods there is an excessive amount of color enhancers used, usually synthetic color enhancers such as Carophyll Pink, which will indeed cause an unnatural coloration of a fish when fed in excess. So much so that it can cause a fish that is naturally yellow, to turn orange, or a fish that is naturally pink, to turn red. This type of color enhancement is quite common in Asia, as are hormones, and IMO if your fish require that type of enhancement in order to look nice perhaps its time to be looking for a better quality fish.
Natural color enhancers used in the proper proportions will only enhance what the fish is genetically wired to produce. Synthetic color enhancers can artificially enhance a fish to the point that they no longer look anything like they would if/when those synthetic enhancers are removed from their diet. Pretty much the same effect as when a hormoned fish is taken off of hormones.
The problem is it is far cheaper for a manufacturer to jack up the color enhancing properties of their feed by simply adding a boat load of synthetic color enhancing agents such Carophyll Pink, etc, than by doing things the natural way. These are the same type of color enhancing agents used by the salmon industry, which is why a farm raised salmon has pink flesh, instead of a bland grey. (guess which ones the consumer choose to eat?)
It all depends on how much is added to the feed, you just have to pick a number from the slick little color chart & dial in what kind of unnatural color that you are seeking.
