I'e been visiting there for a couple of years now - and know some of the fish breeders and suppliers quite well.
If you want ANYTHING to do with aquarium supplies, pumps, filters and of course fish then I recommend the place for a day out.
The travel costs are far outweighed by the savings that you will make if you're buying. In some cases, it's 4 - 5 times cheaper than suppliers in Hua Hin
There is a large aquarium there with a reasonable showing of Thai freshwater fish. You can get up close and personal with a couple of Arapaima and Freshwater Stingray as well as Pacu and others.
An interesting few hours for the kids.
Google Earth location map given below

A couple of Arapaima - about 80-90 Kg each + a Freshwater Stingray at about 30Kg

Feeding the Stingray.........

A nice Pacu - around 15 Kg
