Diagnosis?

[robadk1]

Clown Loach, roughly 3 inches.
Unusually light colored
Reluctant to move
Perhaphs reluctant to eat, hard to tell, one small one eats vigorously, other three don't come right out and eat, but they are very skittish it seems, and perhaphs it's only because I'm at the tank.

Diagnosis?
Thanks for any help.

Clown loaches change color a lot. How long has he been washed out? By this description it could be anything from a sick fish, to a fish that's just had a dominance fight with one of the others. Those fights are usually harmless, but can result in some different behavours for a little bit. Check him and the others for little grey scuff marks, and see if they are interested in treat food. Keep us posted.

Well, it's clear to me now, it's really only the largest of the 4, but I don't see anything that really says he was in a "tussle" or anything. I think they respond a little more to the Hikari Micro Wafers I bought. I recently took out a castle from the tank, because the loach would get so far up in it's peaks, and I honestly don't think they COULD get out on there own. I removed it and retreved them from there. Could that have anything to do with it? Is it perhaphs that I only need to add some slime coat?
