I bought two greenish, slug type critters from the lfs
yesterday. They called them "???? hairy" (can't believe I forgot). I bought them on the suggestion that they are voracious consumers of green hair algae.
Yup, placed them on some algae cover rocks and they went town! Within a couple of hours, the little critters had carved swaths of cleaned rock through the small forests of hair algae. Anybody know more of these critters? I'll call the lfs
back today to get that name if nobody here can ID
them for me.
