I can quote over 10 Cory breeders that use gravel. I'm the type of guy who does my own research and read alot of articles and take bits from everything.
I also don't run heaters and my tanks swing 10+ degrees over a time. Lol. I know I do everything against "the norm" but I have plenty of research to back up each of my decisions.
Have a great day
Clearly some of the articles you are reading and using are inaccurate or misleading. But aside from that probability, a lot of cory breeders use bare bottom tanks, that is another issue enitrely, and others use light sand. But it only shows there are many options--but what you appear to be unable to recognize is that these are specific situations, not the permanent maintenance of a group of fish, that can live as long as 40 years.
The problem with Eco-complete is the sharpness, the grain size, and the biological/bacterial properties. If your research really has been so exhaustive, you would have come across these, and given that they are issues referenced by trained knowledgeable biologists, microbiologists and ichthyologists, they have the necessary authority behind their observations.
|How many of these article authors have ever been to South America to see the fish in their habitats? How many of them have spent years studying biology and ichthyology in order to learn how DNA governs all this? How many have even the remotest conception of how a fish's physiogy operates? People who have done these things are the ones who do know, and any responsible aquarist who cares for the welfare of his fish will take the time to research and learn from them.
And let me make something perfectly clear...I do
not voice my own opinions when I am writing about fish species and habitats. I research and learn from the recognized authorities. This is how society learns and progresses, and each of us must do the same; if we didn't, we would still be sitting in front of a cave rubbing sticks together to make fire. There are idiots and charlatans all over the internet. Learn to recognize the true authorities, and you will have healthier fish and more success.
