Tonight I seemed to notice that his gills are open a lot farther than normal, and much farther than the other fish's gills, like I can see way inside them while he swims. It is possible that they were already like that and I am just now noticing it, but I think it is new. Is this a symptom of something?
Also, he has some white spots on his tail, but not like ich. I have seen ich several times before and it looks like tiny grains of salt stuck on the fish-this looks nothing like that. This looks like little white "smears" kind of? Hard to explain. I cannot see that there is any growth on them like cottony type stuff that might be a fungus, the white areas appear flat and the fin does not look worn or anything. I think these spots were sort of there when I got him but they have become more white since then, although the areas have not become any bigger. I suppose it could just be a coloring thing, but I think they have become more white and I have never heard of a moor getting white spots. There are about four of these spots on his tail. He does have some areas on the ends of his tail that are more grey than blck and so are kind of see through, but these areas look different. I tried to take some pictures but it is really hard to see since the fish is moving and all I have is a cell phone camera. The other fish in the tank seems fine, although she has a bent tail now, where the bottom of her tail is curling in a little bit.
I had another moor originally, but he died about 24 hours after I got him, not sure why.

What do you feed your fish? Omega One pellets, Omega One flakes, peas, spirulina
Any unusual findings on the fish such as "grains of salt", bloody streaks, frayed fins or fungus? As mentioned above, white areas on tail and gills seem open more than normal
Any unusual behavior like staying at the bottom, not eating, ect..? Rests on the bottom ovvasionally but acting normally otherwise, eating/pooing fine
Here are some terrible pics that probably will not help:
This is probably the best representation, it is the little white area in the middle of the tail fin

You can see it here although the reflection makes it look more white than it really is, also it looks liek there is another spot on the end of his tail, but that is just where his tail is more gray than black

One last pic, although you can barely see it here

Thank you for any thoughts on both the white areas and the gills.
