Threadfin Rainbowfish Tank Setup

Design your tank to promote mid- and upper-water swimming by incorporating open swimming areas complemented by plants and decorations that create visual barriers. A gentle water flow mimics their natural habitat, while a substrate of fine gravel or sand enhances foraging opportunities. Moderate lighting can help highlight their colours without causing stress from overly bright conditions.
