How does the heart of an osteichtyes (bony fish) get oxygen?

In the circulatory system of an osteichtyes (bony fish), the heart only pumps deoxygenated blood, so how does the heart get its oxygen? Or does it function without it? How does that work?

The heart of fish has only two chambers. Fish do a single blood circulation. The heart pumps deoxygenated blood through the capillaries of the gill and on to the capilliaries of other tissues, from where the blood returns to the heart.

Through the coronary arteries, the same way yours does. The bloos being pumped thru the heart does not supply it with either oxygen or nutrition.
