have had regal blue tang (Dory) for 2 days and have noticed white spots HELP please Steve :(

Hi Steve, sorry to hear about your problems, is there any way you could get a picture of the fish so that we can diagnose the illness? There are a lot of marine diseases which have white spots as a symptom, are they very small white spots? Like it's been dusted with icing sugar?

It probably already had the condition before you introduced it, but we could still do to know the following:

Tank size, filtration method
Water parameters (ammonia, nitrite, nitrate, pH)
Other inhabitants in the tank?

Thanks

Hi looks very much like icing sugar.thanks steve

hi
tank is a boyu 550 with standard filtration system. We have 1 cleaner shrimp, 1 fire fish, 1 clown fish, 1 regal blue tang, 1 royle gamma 2 sea apples (amy and adam) 2 hermits, 2 emerald crabs. tests done yesterday HigH Range PH 8.4. Ammonia 0. Nitrite 0.25. Nitrate 0.
Many Thanks
STEVE
Ps will try and get photo but is swimming and feeding a s normal.

Hi mate,

Did the shop reccommend the tang? All of the other inhabitants are fine, but to be honest no tang is suitable for any tank under 350 - 400 litres. They grow big and need a lot of swimming space. If they don't get stunted and die then they will bully all of your other fish. I'd get it back to the LFS ASAP and use the whitespot as an excuse. They shouldn't have sold you it anyway without checking your tank size etc.

Hi Steve.How big is the Dory ? Hate to break the news to you but a Dory is on very limited time in a tank your size,and requires lots of space that a 550 cant unfortunately provide.If it stresses and gets whitespot or has infact brought a disease in with it,other livestock in the tank are also very 'at risk'.And in any enclosed tank disease can spread like wild-fire.

Did you get this from a local fish shop - is there any way you can catch it and return it if so as a first line of attack ?

hi
didnt get asked what size tank.
the size of it is about 2cm long (not very big!)
Will try and return to the LFS but will be a nightmare to catch
Many thanks Steve

So sorry

Care sheets here, he does need 'lots' of room http://www.fishkeeping.co.uk/modules/ ... esheet.php?caresheetID=43

Oops!

Sorry to hear that mate........

Hi crackerjack, firstly sorry to hear you are having problems at the moment. Could you just confirm your test results as regards to Nitrite?, did you get it mixed up with Nitrate in your earlier post?, which test kits are you using ?. If you are getting a reading of more than zero then your tank isn't cycled properly. Looking back through your history you don't mention anything about fishlessly cycling your tank. You have stocked the tank too quickly, ie 4 fish and corals in the three weeks since first setting up the tank. If the tank wasn't cycled properly all of your fish are at risk, even if they have managed to avoid whitespot from Dory. Please let us know how things are going so we can help.
