After Dead Fish..

[Esli]

Does anyone know if anything should be done after a few dead fish are found in your tank or stuck on the filter ?
Should a water change be done ? Clean the filter intake ? Anything ?
They were removed as soon as they were spotted, I've been waking up them dead so after a few hours. And its only been about 2 or 3 dead.
My water parameters are
Ammonia 0
Nitrite 0
Nitrate 5 ppm

My guess is that my fish are dying becauss i introduced new ones without being quarantined which those died, and the day after my original school of tetras died after 5 months of having no issues.

I did a water change, 50% yesterday, i did it at temp and primed it like always. My other remaining fish seem to be fine and none of their schools have died.
Thanks

When a fish or a few fish die, it is a good idea to do a water change. You CAN clean your filter intake but there is really no reason to. Um really just do a good water change.
