i have a golden gourami, and a sailfin molly, a zig zag yellow tail eel (about 5 inches long). Are these TOO big???I kept some a while back and they are great schoolers and very attractive. One of my favorite tetras. They are sensitive, but they make a great addition to a tank. Just make sure you don't have any big fish that might mistake them for a snack! I actually had a Bosemani Rainbow that ate a couple of mine before I ended up taking him back to my LFS. I remember coming home one day and being shocked at the sight of a Rummynose tail sticking out of the Bosemani's mouth.
