Greetings and a question regarding deaths while adding new fish.

[Proteus]

Not sure if your picking up from lfs when stock come in or from their tanks. But. If you pick up when shipments come in and take directly home. There is a chance of a ammonia build up in bag and this can burn there gills then they suffocate

I believe.things more likely Trans shipped fish that spend more time in the bag vs fish that come from " local" wholesaler

Also..alk of 7-11 is vague. More a guess?
Imo don't put to much thought into acclimation. It's really only to bring fish upto salinity of your tank.

And api is only good for filling up the trash can
