Brittle star spawed!!!!!!!!

[mrhasan]

After coming back home today, I noticed that my brittle star pulled out the feather duster out of the substrate and was wrapping its legs around it :| I was like WTH!!! I was thinking of taking the star out because it was growing too big and too ugly for my tank and now I had the excuse to actually take it out. So tried to grab it but in the first attempt, a part of its leg came off :| Afterwards, I was able to pull it out of the tank. When I turned on the light to check whether everything is alright, I saw the whole tank filled with mucus :O I tried to clean it manually as much as I can but I am pretty sure there are some of those mucus left (very sticky). So I guess it spawned!

Now I am even more worried since I really don't want hundreds of these ugly stars in my tank :| What should I do? Do a big water change? I really don't want any more brittle star! The one I had didn't do anything to be honest :|
