Yeah I didn’t know the values ahead of time but later I got that information and it was almost identical to my home parameters. They both had swim bladder issues. I’m just left to wonder if it was caused by illness or the plane ride or what.Sorry about your Puffer. That's one problem with receiving shipped fish. If you have any more shipped, find out from the breeder the pH and nitrate level in the tank your fish are coming from and match that in your tank. When your fish arrive, temp acclimate them then immediately upon opening the bag they're in, net or strain the fish out and put them in your tank. If you've already matched their home tank pH and nitrate level, there's no need ro acclimate them. You want to get them out of the bag ASAP once it's opened before toxic levels of ammonia build up in it.
