Interesting... as with fish nutrition in the aquarium, the same with aquarium husbandry, water chemistry, and the like...Funny, I assumed it would have been Tetra Color Bits, which seems to be a fave among discus folks, yet IMHO is a crap food full of low cost low quality fillers. Bio gold I wouldn't think would be an issue, but I have never fed it. Was it the formula supposedly designed for discus? If so I'm surprised that formula would cause gastrointestinal, or swim bladder issues. Seems odd, but I have never experimented with that particular formula.
I used to be a mod on cichlid forum many years ago in the Health/Nutrition folder, I know the author of that article, and own a number of Ad's books, and IMO that diet does not add any nutritional benefit to a diet of TherA mixed with AlgaeMax, in fact, I would say that it falls far short. BTW - years ago in one of Ad's books he stated something along the lines of; cichlids that are only fed commercial pellets will soon lose their color when kept in captivity. That was around the same time the Euro mix was a hot topic. Kind of funny stuff looking back, and just goes to show how little many people really understood about fish nutrition years ago. Unfortunately much of that misinformation from yesteryear still lingers today.
Much of the same out-moded methods are continued without any real analysis regarding their continued effectiveness. Or, for that matter, if the concepts that encouraged these methods were sound to begin with.
Anyways, can your recommend a more up to date text, academic journals, and/or authors on cichlid diet/ nutrition in the aquarium. I am attached to a University so I have access to databases online to research information.
Thank you.
