Gents -
Is there a type of fish that I could add to my 42G hex tank that would end the incredible proliferation of caulerpa that I'm currently battling? It was really nice for a long while, but it's grown a little more than I had hoped and taken over an excessive amount of my tank. I could just use my hands and rip most of it out, but I'd like to add a new fish to my tank anyway, so I'm hoping there is a type of fish that would like to eat feather caulerpa and also strand(?) caulerpa. I think "strand" is the correct name, but if not, it looks like a fern or a very wide and tall blade of St. Augustine grass (I got it from Chris).
The new fish would have to play well with:
1 Yellow Jawfish
1 Tomato Clown
1 4 Striped Damsel (not very aggressive - the Clown keeps him in line)
1 Yellow Goby.

thanks for any help - doug.
