All fish are Ectotherm which means they rely primarily on outside sources of heat to maintain proper temperature, however, there are a few species who can produce slightly higher amounts of heat, either to specific points of the body or it's entirety to aid in hunting or digesting.
Not all fish are cold-blooded. Some fish are warm-blooded such as sharks, tuna and swordfish. As the temperatures in the water changes, the body temperatures of the fish will change also.
Yes,because they live in water and they are not mammals

∙ 13y agoOne reason might be the 'false economy' of having to heat up their bodies. Approximately 80% of human energy goes towards heating our bodies to a stable temperature. However, for fish and reptiles to do this, it may not have been a evolutionary advantage. For example snakes and crocodiles can gorge themselves on one large meal and then not have to feed again for months. This would not be possible if they had a 'central heating system'. Likewise fish would need to devote large amounts of energy towards heating up their bodies in colder water and it makes sense for them to merely adapt to it instead. An example of this is the fact that although fish are exothermic, many species are capable of surviving in large temperature variations (so long as they are not too rapid) that would quickly kill most mammals. Therefore although mammals are warm blooded, they are far less tolerant of changes in temperature that deviate too far from whatever their species ideal is.
~Not really my answer. I accidently deleted the answer before and I had to copy and paste it.

Are mice warm blooded?
Mice, like all mammals, are considered to be warm blooded as they use endothermic methods to keep their body temperature at a near constant rate. This means that they control their temperature via internal means, such as sweating, shivering and panting.
