There is a reason I have purchased 99%+ of my fish not from retail stores. If they sell glo-fish or tiny tankbusters to anybody who asks, I refuse to buy anything from them.
In the past 23 years I have purchased about $35 - 40K worth of fish and I have spent fewer than $500 in retail stores ((I paid $225 for a large clown loach.) This does not include the one high quality very expensive pleace where I traded a BN plecos birn un my tanks for store credit to buy the few fish I wanted. I never used up the full credit and eventually lost it.
I have bought fish imported, wholesale and from breeders for the most part.
I do buy tanks from stores, especially since I ditched glassscages.com because they cold not make deliveries back when due to truck and driver issues. I cancelled my last order from them after 3 months of their failing to deliver as promised, *SIGH*
