yea it's in a flea market format. conditions are poor but venture to say that most animals that are in the pet trade, have seen similar conditions.
compared to Hong Kong, it's arount 2-3 times cheaper for fish that are locally bred. Wild caught or imported fish cost more than does in Hong Kong. Hong Kong prices vary between species vis a vis global prices. For example those azul Pbass, 1ft about 240USD, bags of several largish koi, 6USD, 2 ft long silver arrow 12USD, 2ft arapaima 70USD, 1ft long birchirs 15USD, blue eye pleco 1500USD etc ... most saught after fish are the asian gold or red arrows, flowerhorns, and rays. Baby blk/white spot ray costs about 1400USD. Mind you this is already the market, which sells to general public. So one can imagine prices at the source farms.
yea monkeys, crocodiles, more or less what ever you want, and got the money...
Place is a paradise for fish keepers ... should have a visit if ever get the chance.
