Yes, I agree, a little longer aquarium would be best, for the goldfish ( I kept fish, salt and fresh, at one time ), but the trouble is, that instead if saying, " Hey, I happen to know about fish and things would be better this way, for these reasons.", the approach is an attack, first on one subject and now another. The fact of the matter is that "experts" following easily researched protocol are living off the scraps visionaries and innovaters lay down. Anyone can be an expert, because they regurgitate a care sheet or incubation temps verbatim, but a true expert has not had the way paved by others, has dealt with and overcome challenges, has no ego, and can relate to people in a way conducive to educating them and improving the lives of their animals.
The other fact is, no one knows anything, as an expert, because you can read the often touted blog about chameleon gutloads and have the same person endorsing gutloads with ingredients listed as not advised on said blog, because NO ONE really knows the exact amounts of vitamins and minerals each chameleon needs. There is not a single person better than another here, only ones who know better and ones who don't. If you don't know better than to relate to other keepers on a human level, rather than degrading, accusing, and insulting them, then you are in the same group of keepers that make newbie inquiries in mistakes. I have ZERO respect for anyone, PhD, breeder, long-term keeper, or otherwise, that treat others like they know everything and have the final word. News Flash! The final word is in nature, where chameleons live free of human interference, ego, and opinions, and that's the only "expert" I follow.
