The Niger Catfish (Oxydoras Niger) is the gentle giant of the Amazon. They reach nearly 4’ long though, so a monster aquarium or pond is needed. We have ours in a 8’ long tank right now and that is good but the depth at 2’ is now a problem! The fish has reached 2’ long. We’ll be upgrading to an 8’x4’ aquarium for him in the near future. So be prepared if you choose to keep one of these at home. They are easy to keep in any sort of tank biotope though as they don’t really bother other fish. They are LARGE though, so any plants or decorations will be moved. We use large driftwood pieces and he still moves them with ease.
