There are many blogs focusing on Taiwan tourism, this blog focuses on the aspect of fish you can see/eat in Taiwan.
Koi at Chiang Kai-Shek Memorial Hall
If you visit the Chiang Kai-Shek memorial hall in Taipei, do check out the pond just nearby. There are many koi in the pond, and also a vending machine with fish food for sale (around NT$10 for a tube of fish food). There are various colors of koi, ranging from dull gray to colorful red, white or gold colors.
Marimo Moss Ball Exhibition at National Taiwan Museum
The National Taiwan Museum is not as famous as the other museum, National Palace Museum (aka Gu Gong), but nonetheless it holds some interesting specimens related to Taiwan. When I went there, there was a small Marimo Moss ball exhibition. The Marimo Moss ball were of exceptional high quality (better than any moss ball I saw in Singapore). They were dark green, dense, and almost perfectly spherical.
Water Lettuce Bowl with Guppy
Very healthy looking Water Lettuce specimens in a large porcelain bowl. The leaves were almost perfect, with no holes. There is also a female guppy (camouflaged in the second picture), together with guppy fry living in the bowl. This was seen on Shifen Old Street towards the waterfall.
Koi Pond en route to Shifen Waterfall
On the way to the famous waterfall at Shifen, there is yet another Koi pond with the option to purchase fish food (this time at NT$20). Interestingly, I did spot fishes in the river adjoining the waterfall, but it is quite hard to photograph them due to their color (dull black) and the distance. I wonder what happens if they fall down the waterfall.
Aquarium Shops in Taipei
The most famous aquarium street in Taipei is the one at Section 5, Minquan East Road. Unfortunately, it is not very accessible via train. Despite sounding similar, the Minquan West Road Metro station is very far from Minquan East Road.
I went to a nearby aquarium in Shilin district instead. To my surprise, there was an alligator snapping turtle in the aquarium (together with various interesting species of aquatic tortoises). Just beside the aquarium was a local Taiwanese restaurant popular with locals, with free flow rice and ice-cream. In the restaurant, there are a few live fish and crabs for eating, and there was a moray eel inside!
One thing to note is that Cod Fish (Snow Fish or Xue Yu) is quite cheap in Taiwan, in the restaurant one slab of Cod Fish the size of my hand is just NT$180 or SGD$8. In Singapore, the price is at least double or triple that.
