I am surprised that nobody has separated the two.
I have been to at least 4-5 different Petcos's and Petsmarts in the Baltimore metro area. I strongly prefer Petsmart to Petco.
In every case, IMO, Petco was less sanitary. The only single advantage that I can see of Petco > Petsmart is the $1/Gallon 40 gallon breeder tank sale. Four 40 gallon breeders for $160 and all well made.
As for accurate information regarding fish:
I just read the single WORST description in the history of fish sales from the well respected wholesaler "Seagrest Farms"
According to them:
Alligator Gar - Minimum tank size = 125 gallon
Maximum fish size raised in aquarium =
120 inches.
I kid you not. Go to their website, and see what they are selling to the LFS's as and then bust the chain stores backsides.
120 inches! Are they even aware that is 10 Freaking feet long. They world record in the wild isn't even close.
Just for stinky poops, and grins, how is it responsible to keep a 7' alligator gar in a 125 gallon aquarium?
