+dapettit Posted April 14, 2008 Share Posted April 14, 2008 (edited) I just noticed in the last couple of days brown spots on the sides of our blonde naso. Any ideas as to what this might be? Is it treatable? Or is this a color change? He eats like a horse and is very active. Sorry about the bad pic. TIA, Dave- Edited April 14, 2008 by dapettit Quote Link to comment Share on other sites More sharing options...

+dapettit Posted April 14, 2008 Author Share Posted April 14, 2008 yep. Mysis, brine shrimp, nori and red algae with garlic, vit c and zoecon, and pellets, etc. Quote Link to comment Share on other sites More sharing options...
+ACampbell Posted April 14, 2008 Share Posted April 14, 2008 Sounds like a good diet. Sorry, I don't any suggestions about the spots. Quote Link to comment Share on other sites More sharing options...

cmanning Posted April 14, 2008 Share Posted April 14, 2008 Take a look at : http://www.wetwebmedia.com/nasodisfaqs.htm There's some disease listings there (descriptions). Some closer questions - do any of the spots look "black" or just brown? Is it on both sides of the fish? - or just on one side? Is he still eating happily? Might test the params you normally wouldn't as a sanity test: Ammonia, Nitrite, - just in case something died somewhere, and the discoloration is just a stress reaction. He may have banged himself up racing close to rocks. How many days has it looked that way now? Is it worsening each day? (Take a pic per day so you can compare if possible). Watch your Ca levels - with that new skimmer it could be over-skimming. Low calcium can induce stress anxieties in fish, and this reduces the immune system. If he's acting more stressy than normal (even a little) this could mean some water params are off, or changed abruptly lately. Maybe something you don't normally test for. (dissolved O2 levels ?). Is he generally worse in the morning? --> Check for O2 fall off during the night. - There's a small kit I can loan you to test O2 levels. PH swings during the night ? (plants give off CO2 at night). I am up in the air about what this is, as I have had scrapes and stings by corals discolor our Naso at times (Grey fish tends to show everything). But these have always returned to normal/heal after just 3 to 5 days. Quote Link to comment Share on other sites More sharing options...
+dapettit Posted April 14, 2008 Author Share Posted April 14, 2008 I checked this morning under natural light and it look WHITE! I hope it's not ich. Quote Link to comment Share on other sites More sharing options...
+dapettit Posted April 14, 2008 Author Share Posted April 14, 2008 Robert, I have not made any changes to the water. I had the water tested Saturday to see how far off my Cal kit was. pH 8.1 dkh 7 cal 420 I didn't test for Mg yet. I read the info on wetwebpedia (Thanks for the link) So here are the answers to your questions: do any of the spots look "black" or just brown? they are more brown than black, however this morning the spots appeared to be white (no aquarium lighting). Is it on both sides of the fish? - or just on one side? It's on bothe sides. Is he still eating happily? Like a horse! How many days has it looked that way now? about 3 Is it worsening each day? The same If he's acting more stressy than normal ? no PH swings during the night ? not sure however I run my fuge lighting opposite the tank I think I agree with this comment. I think I will wait it out asn see if things improve.
