Zebra Danio/Glofish getting sick?

[organiz3d_chaos]

Im really confused here, I've had the tank since October, ammonia and nitrite is at 0. Every once and a while I will have a danio or glofish stop swimming around as much, pretty much just kind of swim in place, and quite eating. They also quit eating. This has happened to 3 or 4 of them. Within a few days of noticing this they die. The oldest one I had developed a curved spine about the time she started doing this and died within the next day or two. I don't see any other symptoms though, they don't appear to loose any weight or any thing and the die relatively quickly after it is first noticed.

Also they aren't all dieing at once either, one will do this and die and it may be a week or more later and another will start doing it. Any ideas?


Thanks

Perhaps it is Fish TB?

I think its dropsy/malawi bloat
do they have a distended abdomen

I've suspected that as well, but I see no other symptoms...



To correct my earlier post, I think it is actually closer to 2 weeks between one dieing and another exhibiting the symptoms...


Also, the fish I suspected this morning started swimming around normal and I saw him eating, so it may have been a false alarm, However I have still had around 3 die like this.

it could be then
maybe try checking all the conditions and watch them feed
watch the sick ones closly
my cherry barb died of it try alos maybe putting a little but if a variety i.e flakes and pellets

I was referring to suspecting TB... None have had a distended abdomen.

Fish TB is scary, if it is then it might be best to put them down...it's unlikely you can cure it. Then you would probably want to clean the tank out and everything, but you should probably get some more opinions before killing the fish. I don't know too much about fish TB, but aren't the symptoms-not eating, loss of activity, curved spine (which all of yours have), loss of color and scales, and lesions?

ah ok sorry I didn't know

I've had healthy zebra danios develop curved spines, which is probably genetic.

Whats the tank size?
Tank stock?
Can you post as much of the water parameters as possible?
What test kit are you using?
Whats your setup like?

Only one has had the curved spine, it was one that I had gotten in October and it died this month. None of the others have had a curved spine.
