Brittlestar hitchhikers

[canyon15]

I have just add uncured LR 6 days ago and have been intently watching the hitchhikers slowly showing themselves. My question is are brittlestars considered to be good for your tank and if so do they reproduce at a high rate? I have seen two (at the same time) and don't want to have a tank full of these creatures unless they are just good clean up crew. Thanks for any responses.

Welcome to AquariumAdvice.com!!!
The tiny brittles that generally hitch-hike in on LR are of no threat to your tank. They will eat on algae in the tank and not bother anything else. My 72gal tank I have hundreds of tiny brittles ( I stopped counting) and my 12gal nano has over 100 in it. It seems the more I look the more I see. They are harmless and a sign of a healthy system.
