I am just going by experience for the tetras and danios. That is all. The danios were zebras and the tetras were serpae.SHPEPoser said:I'm wondering if it's the luck of the draw. My friends have an angel with all of there tetras and betta. Also the site under general discussion that lists the chart of what's compatible it says that they are all fine together. But everywhere else I've read says they are not good to keep together. This is why there is such confusion.
