A forest of hydroids

[ref leppard]

If you need another fish , try a copperband butterfly( rock pickers)

I've got them also and been doing quite a bit of reading on them. Seems there's really no way to get rid of them other than the classic nutrient control (but starve them, starve my corals) or manually. The way they started was looking like they were going to take over the tank completely but does appear that the spread has stopped. Hoping that they just might be another phase of the tank and eventually die back.

I have considered removing my rock and hitting the areas with a butane torch but really can't see myself doing this.

It was on Canreef the first I heard of CBB (here post 7). As Potters was also mentioned I followed up in another thread got one but it never made it out of QT so can't say if they might work as well.
