Eeesh - seems like it's been a while - have you heard anything yet??
Don't let the PetSmart haters get you down.
Personally, my local PetSmart is great - except for the one guy who has a condescending attitude.
(He actually does know a bit, but he thinks that since he has this knowledge, everyone should bow before him and no one is worth his time. This is in NO way a stereo-type. It's just the one guy...)
Anyway, good luck. If you truely want to have your own LFS one day, you have to start somewhere. And chains like PetSmart, PetCo, etc aren't a bad option. Even if their fish sales are doing poorly, you're not likely to lose your job. And hey - most fish beginniners buy from those stores, so maybe you'll help some newbies out in the process.
I'll keep my fingers crossed for you!!
