While in Hong Kong, I noticed these pale orange fish busily eating algae like otos. On closer inspection, they looked remarkably like otos in body shape and size (these were 2-inchers) but were that lovely orange/pink color. The lady at the fish store said they were otos of some kind ... Anyone know their species name and whether they may be available here in the U.S.? Greg.
