Could my nemo be sick?

[marcingo]

Hey everyone. Ive got a 55 gal tank with all soft corals. Just before Christmas I added a tube anenome. My inhabitants are two black false perculas a foxface and 2 false perculas and a goby. There is also a cleaner shrimp and peppermint shrimp. 2 weeks ago one of my false perculas dissapeared and I never found a body. This made me think that maybe the tube anenome ate it. The anenome is small and the percula was medium sized which made me think its rather unlikely. Anyway now I noticed one of my black perculas the smaller one seems to be hiding a lot. The colors on its body are dulling out. The other one is very black the white stripes are very bright and its yellow nose and fins are nice and bright. While the sick one has almost lost all the yellow on its nose and fins and this yellow has turned almost grey. It swims and acts pretty normal except for the fact that it hides in the rocks a lot. If anyone has any ideas what this could be and if it could be sick please let me know. My nitrates ammonia and nitrites are 0. Thanks.

Do you notice any aggression between the ocellaris (false percs) and the remaining black ocellaris? In a 55g, there may not be room for two pairs of clowns, and the dominant pair may be harrassing the non-dominant pair.

Maybe the clowns are fighting for turf?

A 55 gallon is big enough for young clowns, but probably won't be enough space for 4 adult clowns.

One might hiding now to avoid getting worked over by the other pair.

Just my opinion though.

Edit:

Beverly posted the same thing while I was two finger pounding my post out.

actually since I put them all in none have been aggressive. They all swim together there doesnt seem to be any nipping or biting and at night they all huddle together.

sounds like ...wait for it... a CLOWN TURF WAR! that was lame but couldnt resist. i have to agree with this

I just reread this - Although the tube might not have eaten your clown, it could have hurt it - their stings are much more potent than a normal anemone sting.

wonder if there's a dead fishy hiding somewhere under the rock?
