White Patch on a Neon Tetra
 
Hi, i am new to this forum and relatively new to fishkeeping too.

Well basically today i discovered one of my neon tetra's has a white patch on its back, it doesn't like look a spot or lump, but is ever so slightly raised. The patch is too big from what i have seen in photo's to be ich.

Now some background information, tank was set up about 2 months ago, and after a few weeks of running empty, 6 neon tetra's were put in, 4 died from a nitrite spike, caused be overfeeding, and so two remained. Then the tank was left a few weeks to settle down, 2 remaining tetra's really perked up. Then a siamese fighting fish was introduced aswell as 2 shrimp. No problems, couple of weeks later siamese turns aggress and is in its own tank. Then 2 more weeks and 7 neon tetra's were added so they would all school. This was last saturday(28/06). All have been doing fine, until today, when i noticed the patch on one of the 2 remaining from the first lot.

Tank was had last water change yesterday(saturday 4/07) and about a third was changed. Water was tested, there were hardly any recognizable amounts of ammonia, nitrite and nitrate. No CO2 is put into the water. Currently using a fluval 200 plus filter and has a flurescant tube for lighting. tank is only about 12 gallons.

oh and there was some chasing going on for a few days after the 7 neons were introduced and there was some this morning aswell

hope someone can help.

It the patch smooth or is it cottony?

Any other symptoms? Is the fish acting different?

thanks for the replies guys. The fish has been removed and put into a food bowl for the minute, quarantine tank is currently housing the aggressive siamese. The patch looks smooth, more like a discolouration of the skin than a something on the skin. I tried to take a photo, but not good enough to actually see it. Other than the patch though, the fish is acting exactly how i would have thought it should.

I tested the ammonia and others again this morning and all are hardly recognizable, so it can't be any of those 3
