unexplained dying in 2 of 3 tanks

[nerdyrcdriver]

Hey everyone, I have my 29g and 10g that are both having issues with fish dying.

The first death was a long finned zebra danio that was in qt. But he seemed to have issues from the start.
The second death was a guppy in the 29g that got sucked to the filter. (aqueon 50)
The third is a long finned zebra danio in the 29 that got sucked to the filter (aqueon 50).

Both tanks are cycled, and my testing shows all levels are fine. ammonia 0, nitrites 0, nitrates are kept below 20 most of the time with water changes. None of the fish died within 3 days of a water change. It was always about mid way between when I do water changes. I use aqueon water conditioner.


The first and second deaths the fish were acting kind of strange before they died. But the third is totally unexplained. He seemed totally healthy. The temp in the 10g holds at 78 with the heater. The 29 doesnt have a heater yet, but the temperature in that room does not change much, and if it does, it is a very slow change. The lowest that tank has ever gotten is 75, but it holds at 78 most of the time.

I was thinking it might be something to do with the water, but my betta in his 5g is totally unaffected by this.

Does anyone have any ideas?

Probably just poor stock.

From what? Nothing happens to the tanks other than water changes and so far none of the deaths have been within a few days of a water change.

When you transport a fish from the store, and from tank to tank it can be stressed... New surroundings, tank mates, water parameters, etc...

All of the fish were in the tanks for 2+ weeks before death. Although, they all did come from the same petsmart other than one male guppy who is totally fine.

If they were stuck to the filter then they were probably already dead. Chains are notorious for bad genes, and I too have had fish bought from them just plain die sometimes.

+1 I've had fish die on me after being in my tanks for 3 weeks or even more. That usually happens with schooling fish.

I am just trying to figure out why they are dying. Other than just plain bad genes, it would almost have to be something wrong with them inside.

On the plus side I just got my grocery store dwarf flame gourami to eat. He was fine eating the food, it was just getting it to him. I couldnt let it float, he wouldnt go get it and the danios would eat it. He got spooked when I walked up to the tank. This time he went under the heater. I shut the filter off, and held the food under water to get it to sink to him. He went to town eating it

Id call the coroners office, and see if they can do an autopsy, that way you can get this mystery solved once and for all.
