I am still doing plenty of research for the lifestock in my 20 gallon. How would a linkia Starfish be? As of now.. I have live sand and live rock. Those starfish are my favorite. Anyone have experience with them or know more. I'd appreciate it. Thanks
Linkias need a large amount of live rock to survive. They do not feed on the usual food we provide. I would not recommend one in a tank smaller than 200 gallons.
For a 20 gallon a serpent star will be OK as those really feed in whatever we offer. Other than that I would not recommend any star fish for a tank that size.
