In order not to hijack this thread, I have opened another to do a discussion on this topic. Sorry RTR, I understand your frustration to having explain this again and again and again. pls tell me what I did wrong in the video. Link below.RTR wrote:Sorry if I stepped on toes! I really did not mean to attack or upset anyone. But that explanation of the phantom reflections is one of the commonest tank myths.
There is light reflection from bare bottom glasses, and/or shadows from the fish which can startle or spook them. Some bottom covering for me makes the fish much more normal in behavior. Only pelagic or ultra-deep FW fish see no bottom. Most of our hobby fish definitely see the bottom of their world and may see shadows but underwater bottom reflections have to be rare in the wild but universal in substrate-free tanks.
If I do a blurb on side-glass reflections, will Dadof4 shoot me? Diagrams and photos? Can the library take that?
