Green brittle star...reef safe?

[djessem]

I need an answer to a quandry.... I have a 90 gal reef tank and in it lives a green brittle start that is about 24 inches tip to distant tip......is he going to be more of a hindrance by knocking things over than the asistance he provides by keeping the underside of the rock work cleaned........can he stay or should he go ?

It depends on the individual sea star. Some of the big ones will start eating small fish. Some will continue to be peaceful.
If you have had it for a while you should know if it has caused any problems.

The green brittle have been reported to be a bit more on the aggressive side especially after they've gained some size. I've got a darker colored brittle than has been in my 55 for well over 30 months. I strongely suspect he has munched severla crabs/shrimp and I won't be moving him to the new display. Instead he'll complete his life in the 55 which will soon be the refugium for the new display.:thinking:
