Due to the fact that Las Vegas is a desert and the tropical fish scene is just not what it would be in LA or Boston we only have 3 or 4 fish shops that are not the big box stores. (shipping fish to the desert kills everyone)
With that said the team at Trop does their best to find some cool gems to fill their tanks. They have a modest SW selection and also stock some FW oddballs.
The prices are fair but you may need to do some haggling to get the best prices. The staff is knowledgeable and always eager to help.
They have a fair buy-back program and will special order just about anything you'd like. They always have a full feeder tank as well.
I would give them 5 stars but there is not a fish shop in LV that could meet that mark unfortunately.
If you have tanks a weekly stop into Trop is not a bad idea. Also on Tuesdays its 2 for one day on all fish under $10.
Give it a look.
