There are two types of food poisoning that you can get from eating fish. They are Ciguatera poisoning and Scombroid poisoning. Ciguatera poisoning symptoms include stomach cramps, nausea, vomiting, and diarrhea. Symptoms can include headaches, muscle pain, and skin itching, tingling, or numbness.
Some common characteristics of bad fish are a slimy, milky flesh (a thick, slippery coating) and a fishy smell.
