Got this plant as a throw in from something I bought. The seller said I can put it in one of my sump compartments. But I'm scared since I've heard the caulerpa horror stories anyone know what it is??????
Does it have runners? Not sure from the pic, but it looks like turtle grass (thalassia testudinem). However, if it's a calurpa, it's most likely C. prolifera which can become invasive, but not as badly as C. racemosa or C.peltata.
