I won't be saying all I think about that store, cos I will be banned right away..... so so mad... poor little guy, so sorry for your loss.
yes you should always do your own research, but usually you are getting this after years of having reptile/frog, usually first time owners just go to the store and listen what "knowledgeable" associates tell them to do, they know how to talk and pretend they know what they're talking about, so you trust them unless you know otherwise.
Silverspring you did great by joining forum, you'll find tons of advice on everything. it is way better then just to buy a book! in fact you won't even need it if you spend enougth time on there and always ask if you have any questions. welcome!

I really hope your BF won't lose his too.
