What will eat sponge?

[ISpeakForTheSeas]

If I don't siphon it out would it spread?

Forgot to answer this earlier - it depends on the species and conditions of the tank, but it's possible, yes.

Also, is the one mentioned in the post, Terpios hoshinota, Only effect SPS?

T. hoshinota can effect pretty much all stony corals (SPS and LPS). I've heard of one report of it harming soft corals too, but I haven't been able to access the report to learn more about that yet. It prefers live, branching corals, though, so it typically prefers SPS corals.

Which fish could eat pineapple sponge, but would leave my soft and LPS corals alone? Also, small tank (125L/33g)
