Hello! A while ago I came across a website called MJSreptiles. They sell, as stated in the title, reptiles, but also inverts and fish. He has several saltwater native fish for sale and I want to get some but I’m not sure how reliable he is. The reviews seem pretty good but I think that hearing from people who have bought from him are a better source for info.
Many things take time; I accept that and don't fret about instant gratification.
