The case of finding Ameca splendens that are "wild caught" is indeed interesting Fish48. Although I have a tank of Amecas, I am well aware that no Ameca has been seen in the wild in over 20 years. The IUCN lists them as extinct in the wild with a last siting that was quite long ago. They are delightful fish and that is why I keep them but any shop that doesn't even know a fish is extinct in the wild had better not try citing the source of their fish. BTW, that is a nice looking female that you have.
Markk039, if you want some decorative fish that are a little harder to find, why not look into something like Characodon lateralis. They are quite colorful and also are easy to care for. My own have collection information and are happily living and reproducing in a 29 gallon tank. The nice red fin edge colors add a lot to a tank when my wife constantly remarks on the simple looking fishing minnows in my tanks. At least she can appreciate them.
