Red Knob Sea Star
Protoreaster linckii
The Red Knob Sea Star is a beautiful and different starfish with contrasting colours. Only one should be housed per aquarium due to their feeding habits.
It requires a tank of 400 litres or larger with plenty of unobstructed rockwork to feed off, it is not as bendy as other starfish so rockwork must be accessible for it. This star isn't reef compatible and will eat orals, sponges, tubeworms, clams, and other inverts. The red knob stars are sensitive to aquarium conditions, and won't tolerate big fluctuations in sg, pH and O2. Due to this weakness they should be drip acclimatized over an hour
Approximate Purchase Size: Medium 8cm - 10cm
