It depends on the fish. Most fish are cold blooded, but a few are not. Several species of tuna, for example, are able to maintain their body temperature within large range but above the temperature of the water around them.
Well Actually, bluefin Tuna and some other species are neither warmblooded nor coldblooded. They are species in between, meaning that they selectively warm parts of their body.
Also the Tuna does not spend energy to keep warm like warm blooded animals, it just has two specific sets of thin blood vessels that work as heat exchangers. One close to the brain and one close to the tail. The tail heat exchanger warms the blood coming cold from the gills, by passing it next to the warm blood, going from the hot tail swimming muscle to the gills.
Almost all fish are cold blooded. However, some species of Tuna are able to maintain a body temperature above the ambient seawater temperature using a special organ called the 'rete mirable'.

Most fish are cold blooded, though there is evidence that some sharks may be warm blooded.cold blooded
Cold-blooded While most fish are cold blooded, not all are. Some fish - like the tuna - are warm blooded.
Clown fish are cold-blooded.

no, they are fish and therefore cold blooded
Starfish are cold blooded.
warm blooded
A pufferfish is not warm-blooded. All fish are cold blooded.
They may be both. Mammals and birds are vertebrates which are warm-blooded. Reptiles, amphibians and fish are vertebrates which are cold-blooded.
Fish are cold blooded.
As with the vast majority of bony fish, flounders are exothermic or cold-blooded.
