Why are my fish die ??????????????? I had an albino cory with tropical fish for about two months and never had probolem .. 3 days ago I had to put all my fish in a smaller tank for an hour so that I can do a water change of 50%. I do 25% once a week, but I had a new filter and I'm still cycling. Do you think it is stress? I made the water change three days Thank Ogo
Do not listen to these people. A water change of 50% is sometimes necessary, and should not interfere too much. A water change of 25% is often more effective, but there is nothing wrong with 50%. People with a frying pan will change 75-90% of the water once a week to keep bioload.
But when you do a water change of 50% there is no reason to remove your fish. Get the new water ready in advance about the right temperature, dechlorinated, etc. Then siphon the water with a gravel vacuum, just move slowly and be sure to make only one zone at a time for fish do not feel like they are chased everywhere. Then, you can pour water in the news, just do so slowly so that the current is not too strong. Sometimes I put it in through the filter to ensure it does not bother them too much.
I'm not really clear why people put their fish in a separate tank to clean the tank, but as I noted to answer dozens of questions about it here, if you do it long enough, you'll problems. It causes more stress to move a fish other than to leave them in water for change. Normally, you move the fish do not have a lid, and they are already stressed and in confined areas, so fish jumping is not uncommon. It is really best to let the tank.
It's too much of a change of water. The change in water quality probably killed the fish.
Yes, it was stress, and the poisoning of ammonia. If you got a new filter you have started the process of bike again, and the accumulation of ammonia has probably killed the fish. You should also never move your fish to change the water. That the stress. The container has probably not been much oxygen is.
It was most likely a combination of the new filter and large water change. You probably induced by a mini cycle.
