The range of tetras exported from South America has been steadily increasing over the years. In this article we’ll be looking at some of the less familiar tetras currently imported. While most are eminently suitable for the community tank, some have particular needs that make them challenging in one way or another. These tetras also tend to be wild-caught rather than farmed. On the one hand, this means that they are less likely to suffer from inbreeding or disease, as is all too often the case with intensively farmed Neon Tetras and the like. But being wild-caught fish, these tetras are often fussier about their food and less adaptable in terms of water chemistry, so appropriate care will need to be taken when settling them in.
