| Your tank will likely have to finish going thru it's initial cycle, and depending on how much live rock you added, it should go quickly now. Live rock is a great way to speed up a cycle. Hopefully, there's not too much ammonia or nitrites. They should be able to tolerate a little bit of either, but more than traces could be fatal. They should be kept in good water conditions. Hopefully, your water is cycled enough that with the live rock, there won't be enough of either toxin to harm the star.
By the way, almost the only part I ever see of my 10"+ brittlestar is the thinnest parts of it's tentacles as it sweeps around looking for tidbits to eat. |
