There are several animals that bioluminesce, but none suitable for a standard tank. All would need species tanks, and frankly even if you did it, they would be, frankly, very boring in short order.
Flashlight and pinecone fish are two of the more common types, but again, not suitable for typical tanks.
There are several bioluminescent animals, such as the small hitch hiker brittlestar Amphipholis squamata. But these are often defensive behaviors that are things you would likely not see unless you were looking in the right place at exactly the right time.
There are (unfortunately, IMO) bioengineered fish - I believe zebra danios (a freshwater fish - you may remember more Jon...) that "glow" due to the insertion of a gene.
