Threadfin Rainbows Pair

Threadfin Rainbowfish are hardy fish that can be kept in various aquarium conditions. They are tolerant to a range of water temperatures and pH levels, making them an ideal choice for both novice and experienced aquarists. In addition, Threadfin Rainbowfish are peaceful fish that do not typically harass other inhabitants of the aquarium.

The ideal temperature range for keeping Threadfin Rainbowfish is 73-84F. Rainbowfish will do best in slightly acidic water with a PH of 5.5-7.5. 

The minimum recommended water temperature for this species is 73°F or 22°C. Threadfins are very cold sensitive, so the water temperature should not drop below 68°F (20°C) at any time; if necessary, heaters should be used to maintain warmer temperatures.

Threadfins prefer water hardness in the range of 5 – 19 dGH
