I got a new 10 gal. tank and set it up 21 days ago and had 3 Zebra Danios and they were fine for about a week and then I lost one. A week later I lost the second one. I have one left.
I am using products from a large Canadian Aquarium chain i.e. store brand. The water conditioner treats
chlorine and Cloramine and has Aloe Vera for "slime coat" enhancment. I also used a Bio-support product that has beneficial bacteria to get the bio-wheel filter going.
Here are the details using
API test kit:
-
ammonia is 0
-
nitrite is 0
-
nitrate is the lowest color or next to lowest
-
pH 7.5
- Water Temp was 77 now 75
The symptoms were the same for the two dying fish (a week apart):
- Tail droops up a little. They swim tail is straight, they stop tails droops up, they swim some more etc.
- Color is not very vibrant. They look a little pale. Not obvious white spots unless the whole fish is covered with a light haze but its hard to tell because I don't know what I'm looking for.
- Gills are red but not all the time it seems.
- Fins and tail look a little "flimsy" for lack of a better term but maybe that's normal for this breed, I don't know.
- They start treading water in the middle of tank and stop eating for a day or two later they tread water about an inch from the top and then die.
I am stumped. I know I got something going in there but I can't identify it. Is there a place where I can see photo's of disease so I can identify it ?
