I am currently employed at store #1380 PetSmart, Palm Springs, Ca.
For what it is worth to anyone here, I work in the PetCare/Specialty department at PetSmart. While I came in with prior aquatic knowledge, the rest of my staff had not, and our organization was moderately in-depth with training about the various rules to fishkeeping and showed an overall concern that their employees be knowledgable enough to keep the trend with increasing responsibility with regards to fish wellbeing.
As in any store however there are the few who just don't care and are irresponsible, but overall, PetSmart seems to have become very rigid in making sure people don't just disregard a fish's health for the benefit of a buck.
I have turned many, many, many............. customers away from making just the most stupid mistakes with their fish.
"No sir, you cant keep that many fish in a 3 gallon"
"No, goldfish cannot live in a 1/2 gallon bowl"
"No ma'am, fish do not grow only to the size of their tank"
"Because....they will EAT them!"
"NO!"
I care.
