Peter's Elephantnose Tank Setup

Plan for at least 66 US gal min of water—that is the minimum in our database for a workable setup, not a challenge to crowd fish. Aim to hold 73–82°F and pH 6.5–7.5 without daily drama. These fish use the Mid zone most, so put wood, plants, or open water there accordingly.
