Dead rasbora

[Colin_T]

I added a zebra nerite snail a few days ago to deal with se algae, could it have passed something on the fish?
Tap water is always dechloronated.
I clean the filter every couple of weeks, I was a few days early this time than two cuz of what happened with the rasbora. I usually disassemble it all and clean each part individually in water from the tank or dechlorinate tap water, is what I'm doing wrong??

Ps- cloudy water in video and photo is because we added será bio nitrivec

Snails can transmit some diseases to fish but it's uncommon. If the snail came from a tank with fish in, and the fish had a disease, the disease organisms might have been introduced with the water.

The filter cleaning seems fine.

You don't need to add the Sera Nitrivec after the filter has cycled. You can put the remained in the fridge or pour the rest in the tank and don't buy any more unless you want to set up another tank.
