Danio died, one more seems to be gasping.
Hi, I recently moved my 5 danios to my 90gal to help cycle it. They were happy and normal. Today I did a large water change and noticed afterward that they were not swimming all over like they normally do. We went out to get a movie and when we came back one was dead :(. He looked healthy, no sign of disease. Now I am worried because there is one other one who is swimming around the top of the tank, slowly. The other three seem to be ok. Levels are currently:
Before I did the water change the PH was around 6.4. Could this PH spike have caused the fish to die? If so, what do I do now and how do I prevent this in the future? I think this other one will die soon, he does not look good.
the quick change could have and the other thing that comes to mind is not enough oxygen. fish swimming at the surface gasping is usually a good sign of low oxygen levels. do you have a good air pump and air stone/pipe?
No air pump but the output of my canister filter is above the water level so it agitates the water.
So far so good. So how am I supposed to do water changes to avoid this in the future?
I would perhaps stick to small but frequent water changes at the moment to prevent large fluctuations in the parameters.
Hope the fish are ok :)
The remaining 4 are OK this morning. Weird thing is that the one who died was really pale and small before I moved them to the 90gal. Once I did his stripes came out and he looked great....then he died. So my guess is that he was weak to begin with....
Sorry to hear about that jsm, best of luck to the remaining danios.
Sorry to hear about the loss of the fish. How large of a water change did you do? Do you add dechlorinator to the water?
I know the water from tap contains CO2. As it sits, the CO2 is degassed, which will cause a change in pH. That small of a pH shift should not be a problem for the fish.
sorry to hear that
i hate it when fish die
it's like losing a piece of yourself
hope the other fish go well
