Searching for information on this gets frustrating. S: 鱼豆腐; T: 魚豆腐 (yú dòu fu) means 'fish tofu'. Searching with or without the quotation marks returns many dishes of fish and tofu together.
Not necessarily a bad thing: S: 鱼头豆腐汤; T: 鱼頭豆腐湯 (yú tóu dòu fu tāng), fish head and tofu soup is one of my favourite Chinese soups.
You also get fake fish made from tofu for vegetarians, vegans and vagrants.
No. What I'm looking at today is fake tofu made from fish. This is occasionally available in supermarkets and used in hot pots, soups, stir fries etc.
Fish tofu can also be made at home. This recipe is Korean but it's the same as the Chinese version and is the best recipe I've found.
