I have a 30 gallon fowlr sw tank.
Currently, I have 2 damsels in it.
Someone in my area is selling 2 red and 1 green brittle stars on craigslist for cheap.
Does anyone have any experience with them? Should I get one for my tank?
Brittle starfish are nocturnal. Ie you will not really see them during the day. They are great at sifting through the sand and eating left over food. They are reef safe , but should use caution with slow moving inverts and slow perching fish. I would not pay anything over $6 each.
