I have a ten gallon tank and a pinguin mini filter, i use tetra something or other to condition the watter and yea i change the watter about 2 aweek doing 15% watter changes,(have free time)and my fish is a 2 inch black moor. but anyway my problem is, when i got my fish he one scale on his left side turned gold other wise looks like it is missing, cause its really different from his dark black coat, and well now a couple days later more scales are starting to turn the same shade, its really wierd, any possible i deas, i have heard that black moores turn gold over time, but this is wierd cause its only on his left side, so i don't really know whats up, if some one could help me out that would be great...
