Hey all, I recently got my first tetras, 8 head and tail light tetras. At the moment they are in a 20g with 3 bronze cories and a small female fire mouth. They all get along great, and sometime this year, I will be upgrading to a 3ft tank. Not sure what the height or width will be. When I get the bigger tank up and running I will be looking to add a few more fish. I will be adding 3 more cories, and some more tetras. Now, my question is, with regards to the extra tetras, should I get some more head and tail light tetras, or a different type? If I got different type, what would be the best? Preferably a mid sized tetra. The fire mouth has so far shown 0% aggression, and has been with them for quite a while, and is about 3in, but I don't want to tempt it with something small like neons or rummmynose's. I'm fairly new to tetras, and I'm used to keeping large cichlids in solo tanks, so I'm still learning the in's and out's of community tanks. Cheers, Jim.
