The original complaint on this thread was against a local Petsmart, but they do have the one of the cleanest pet stores around. The local Petco on the other hand is not so good (there's where I purchased all my frogs) They are understaffed and as stated earilier, they keep getting more WTFs in whether they need them of not... so I wasn't concerned about buying one that was in need and them taking that as a demand for them and ordering more.
There is another Petsmart in my area and their store is beautiful and the the WTFs are in at least in a 30 gallon tank and only a couple are in there at a time... so I guess the blame goes to the individual store managers? since there are good and bad Petcos and Petsmarts around.
