Neons Drpping Like Flies....

[big mick]

I decided to re-home my breeding pair of green severums and turn my 300ltr back into a community tank again.
Its been running for 2 years and Ive had very few problems with disease.

Once the severums were gone i was left with my red ram, 3 juli corris and my dojo loach. I did a water test and the results were

pH 7.4
Nirtite 0 ppm
Ammonia 0ppm
Nitrate 10-15ppm

Since the tank is well matured and the stats appeared fine I thought Id get 20 neons to begin with ( ended up getting a couple more free aswell). That was yesterday, when i got home today at 3pm 6 were dead and a few not looking too clever, now another 6 are dead and another 2 dont seem to know what direction they want to swim.

being a newbie I dont know alot but from what I have been reading neons are very sensative so if your water it pretty different to that of the lfs where you got them then that could cause them to drop like flies also it may be neon tetra disease which is pretty common I think but I dont know alot about, sorry its so vague but I dont know a lot.

Did you put the tetras directly into your community tank, or did you place them in a quarantine tank?

That's a lot of fish to add to your tank at one time.

If you did witness erratic swimming, restlessness, discoloration, it may, as stucolls suggested, be neon tetra disease, which can affect fish other than neon tetras. You must remove any ill fish immediately or the disease will spread rapidly through your tank. There is no known cure.

I would probably return all of the fish to the lfs.

I would tend to think that was a problem of acclimation or something to that extent. Even though adding a large number of fish at once could cause a mini cycle, it would definitely take more than a day for the ammonia to poison them. Could be that they water they were in at the LFS was much more acidic than your tank and the acclimation process wasnt long enough to allow for them to adjust to the higher pH.

wicked!!! (not for you or your fish) but thats what I said!!

so as a newbie I have learnt somethin! I knew it wasnt too late too go back to school

From what I know, Neons are actually not very hardy. I lost a few early doors for no reason at all. In a tank that size thats matured, its probably not ammonia. Did they lose any bands of colour prior to death ?

Could well be a change in water hardness, PH etc. You could add some melafix with them, I always add it when adding new fish, I know alot of people say its rubbish, but ive had good results with it in the past.
