I really dont know what fish to pick, i really want an angelfish, but i also want a pearl gourami. Ive been told that they arent good to have together. What are your opinions? I have a 37g with Marineland Penguin Bio-wheel 200 with 3 red wag male platies. I plan on adding 4-6 Corydoras and 3 female platies in various colors. So...The Angel? or the Pearl?
