I have a brackish tank, 35gal. with a knight goby and 4 cichlids. They all seem to be getting along better than anticipated. However, the other night while feeding them, I noticed that my goby has a white spot on top of it's head. It doesn't look fungal, but I'm not a biologist. I added an aeration system about 2 months ago, I'm not sure if that would necessarily be harmful, I personally think it would help with sediment. I did a water quality test, everything was good but my nitrates are dangerously high. I suspect that this may be part of what's wrong with my goby. I'm just wanting an opinion if that would in fact be a possibility or if my goby is indeed infected with something. All the other fish seem just fine, so it's just effecting the goby.
possibly ill knight goby

Can you upload a picture of it?
What kind of Cichlids do you have?
How much salt do you have in there?

I uploaded 3 pictures of the goby.
I have 2 convicts for sure, 1 white cichlid (which was given to me, I was told it was an albino convict) and a small black and blue spotted cichlid, I don't know what kind it is.
I put 7 tbs of marine salt in to make it brackish. Stirred it in hot water trip dissolve before adding it to the tank. I was told that the cichlids and catfish would be fine in low to moderate brackish conditions.
Keep in mind, I've had the goby in this tank for the past 5 months or so with no issues at all until the other day.

Where are the pics
Cichlids are normally kept at a lower salt content then brackish water. But sa Cichlids isn't my thing

I posted them on my profile.
I had a pet store clerk tell me that she's surprised the others are doing well in brackish. I just went by what I was told before and it seemed to work out, I may have just gotten lucky though.
