Udotea Control

[hollback]

I have a 75 gallon display with mostly SPS. Within the past few months my rock has been over run by Udotea sp. I also have an abundance of Valonia which I can deal with. After some reseach in this forum, most suggestions point to urchins. Would a long spine or a pin cushin be a better choice? Are there other preditors that might help control/eradicate the Udotea?

Current Livestock include:
Scopas Tang
Lyretail Anthias
Green Chromis
Manderin

20-Nerite
15-Astrea
Turbo Snail
Electric Blue Leg Hermit
Blue Linka
Sand Sifting Cucumber

I would think the Scopas might eat it. Are you sure you have Udotea?
