Death Number 2.....

[Behold]

Ok this time i just lost a zebra danio. i belive it was a she and she seemed a little rounder than most but not bloated. she slowed down last night to not even react to my hand near the tank. thismorning i found her stuck to the filter head dead. i took her out. ALL colour has gone and on the belly it is soft with minor red patched.

Is this just fast acting dropsy? some rupture there are no markings on her at all.

new and existing opaline are now fine RTBS is finally not such a recluse! and the 2 gibbs are nice and active. at least 3 danios are always active. bit concerned that a couple of the other danios seem to not do alot but will react to movements around them.

I don't have a hospital tank at the moment and need to get one. should i get a breading tank to isolate them in just to monitor them???

Thanks

Oh ps.

The Zebra Danio didn't have Dropsy, Her stomach wasn't swollen, Was it?
No, I wouldn't get a breeding tank, Just a normal tank. It doesn't have to be very big either.
Are you adding any more fish to the tank that all the other fishes are in? Because you can, But you should add some Mela Fix to the water for 3 days. 1 tsb. per 10 Gallons I think...So if they are in a smaller tank, Just give them a VERY small drop.

Good luck with your fish!
Hope I helped!
