Violet Goby--Drooping Dorsal  3/2/07
<Hi, Pufferpunk here>
I've had my violet goby for 5 or 6 months in a 30 gallon tank in brackish water.  It eats normal fish flakes or pellet--anything really. In the last 3 or 4 days it seems that its top fin has dropped down from standing up and I was just wondering why?  If there's to much ammonia in the water or if my other fish are bugging it?
<What makes you think there's too much ammonia?  Have you actually tested the ammonia? Please write back with the following in your letter: Exact test results for ammonia, nitrite, nitrate, pH & specific gravity.  How much salt are you using?  Are you using marine salt?  Who are it's tank mates?  You might want to look here:

Also, in your return letter, please use proper punctuation, capitalization & spelling.  I have corrected this one, as it will be posted in our FAQs.  The next letter will be returned unanswered, unless this is done.  It is exhausting & time consuming, for me to correct every letter someone sends here.  Thank you!  ~PP>
