Threadfin Rainbowfish

The Threadfin Rainbowfish is one of the more unique rainbowfish and will display a variety of different colors once healthy and established in your tank. These fish come from streams & rivers across New Guinea & Australia, so they are a hardier fish that can adjust to fluctuating water levels (KH, GH, PH, & temperature) It’s best to keep these guys in a school of 6 or more to keep them feeling safe. They will usually not adjust well to lower hardness tanks!
