help fish dying

[dav58]

please can somebody help.
i bought two percula clowns a fortnight ago.i acclimatised them using the drip method then put them in the tank with the lights on this was on a thursday evening,fed them friday everything seemed ok all weekend got home from work monday morning checked the tank as normal,again everything ok this was at about 6.30am looked again at 7.00am and one of the fish was swimming upside down and going to the surface for air,by 8.00am the fish was dead,the second fish seemed ok but on thursday almost exactly the same happened again with this one.
now i can see little white specks in the tank they dont seem to be swimming or floating but rather crawling on the glass.
i thought it was a bit weird that four days after getting the fish one dies then four days later the other one dies.
all tests were done on the water everthing normal.i also have two corals,two red legged hemit crabs and a cleaner shrimp all of which have been in for over a month now and all seem to be thriving.

any help will be appreciated as i daren't get any more fish till i find out what is wrong.

Hello, and welcome to reefs.org. I don't think the specks you're seeing have anything to do with the fish deaths. Unfortunately, without more information on water parameters, etc., we can't really offer up much of an opinion.

I think you're wise to wait on getting more fish til you sort out the trouble, though.

sorry about lack of tank details.
tank size=48*15*12 approx 30gallons(i think)
using undergravel filter seeded with live sand plus a fluval biolife filter.
no live rock as yet.
ammonia between 0 and 0.1
nitrite 0
nitrate 12.5

water circulation is done by the biolife and a maxijet 1000
lighting is 1 marine blue flourescent on for 10 hours
and 1 coralife 10,000k marine white on for 8 hours

i have looked elsewhere on this site and found out the white specks are copepods/isopods or some other kind of pod.

so far everything that i have read is pointing me towards clownfish disease although there were no external marks on the fish at all

It can move very quickly, though. However, with Brooklynellosis I would expect more "presentation", you know? This is a stumper..

You may want to try acclimating some black mollies to salt and try them for a few weeks, see how they do.
