Bump the old OTO thread night lol.
Anyhow I got 3 OTOs for my 10G a little while back which has some shrimps, betta, couple guppies, couple golden pencilfish. Of the 3 OTOs 2 of them for some reason like swimming with the pencilfish. One of them does it alot but have scene the two more active OTOs do it together with the pencils. From a distance they have similar markings I guess. The pencilfish dont seem to mind either.
They arent trying to suck on them or anything either, just swim up and hang out for a little bit bounce around then go back to hanging on whatever (glass, leaf, rock..)
