The Red Knob Starfish is a fascinating addition to any saltwater aquarium. These beautiful creatures have a bright red body with knobs on their arms, making them a striking and unique addition to any tank. They are also known for their scavenging behavior, which can help to keep the tank clean and free of uneaten food and debris.


The Red Knob Starfish is a relatively hardy species, but they do require specific water parameters to thrive. They need a tank with plenty of live rock and a sand substrate, as well as a good filtration system to maintain water quality. They are best kept in tanks with a moderate to high water flow, as this helps to mimic their natural environment.


In terms of diet, the Red Knob Starfish is a scavenger and will feed on a variety of meaty foods such as shrimp, crab, and fish. They will also consume any leftover food in the tank, making them an important part of the cleanup crew.


The water parameters for the Red Knob Starfish should be maintained as follows:

  • pH: 8.1-8.4
  • Salinity: 1.023-1.025
  • Temperature: 72-78°F
