anybody know of anything that will eat away the caulerpa from smothering corals? Preferably something small

[Waterlogged]

I had red and green caulerpa. I bought a copperband butterfly. I no longer have caulerpa.

something that can fit in a 29?

[graveyardworm]

There isnt much that will fit in a 29 which will eat caulerpa. Caulerpa contains a toxin called caulerpenyne which deters most herbivores from eating it. You could try to remove as much as possible by hand and the use a small urchin, or possibly even emerald crabs to eat it as it tries to grow back.

I have two tangs yellow and blue and they eat it until it is all gone.
