Quinn, yeah, he's still around.
I don't always see him now but I'll catch a glimpse every few days, and then I get all excited. "Hey there's Sluggo!"
Beth, I can't remember what the brand name is of the wafers I used. You should be able to find them at your favourite LFS. When I get home tonight I'll check the package and let know the brand name. But if you just asked for "algae wafers" they should know what you mean.
Unfortunately I don't recall precisely at what point mine starting nori. I always have a 1/4 sheet of nori in the tank (well .. maybe not "always" per se but I put ona new sheet at least daily .. sometimes 2x/day if the first one gets eaten quickly enough ... it doesn't take long for the tankmates to eat it down to nothing). But anyhow, it wasn't right away that it took to nori, perhaps several months. He must have just tried it one day and discovered that he liked it.
