Interesting topic really and unless someone can temporarily become a fish it's something that can only remain as a theoretical discussion.
I'm certain that all creatures with a brain are capable of the simplest emotions such as anger or excitement but for fish i would think that emotions would not be of a very complicated nature given their usually small brain size. I would strongly disagree with anyone who thinks fish only have an 8 second memory though.
As we progress through larger animal species with larger brains i think they become more capable of a recognizing a greater range of feelings. Almost anyone with a smart dog will be able to recognize when their pet is acting in a few different ways. My sister has a maltese X fox terrier who will ignore you for certain things. He gets offended if you take his toys away and will sulk for about an hour afterwards. Everyone is his friend except the person who took the toy. He sulks if he is not invited for short car trips in that if my nephews and nieces go with their mum and he is not invited he will not greet her when she gets home while he jumps all over the kids. After long trips this isn't the case, my sister is usually the first one he greets after long trips. He gets jealous if you pat another dog while walking at dog parks. He is a temperamental little dog to a larger extent than any dog i have known.
