I am having a problem in my tank for a couple of weeks now, and I've been
trying to get some help on other groups since it is fish-related. I just
read a post here alluding to otos going after the slime coating on other
fish. This is something I wasn't aware of..

First my tiger barbs, now most of my fish, are scratching against plants and
the heater, etc. I've seen some things that made me think gill flukes (esp
the tiger barbs' gills look discolored). This is the thing... my dad
yesterday said he saw an oto attach to a fish briefly. I didn't think much
of it. There is still plenty of algae in my tank, both green spot and
diatomous (sp?) brown and I've never seen them doing anything but eating
this.

Any thoughts on this? Thanks!

ps - no ich spots anywhere
