Do Fish Lay Eggs?

So Grayson has been adamant over the last week that Harry Beta-Fish has laid an egg. His cries have been met with a lot of eye rolling and "Go to bed, Grayson." We thought it was just a ploy.

Today, though, I finally replaced Harry's broken home from Lucie's earlier fishing expedition, and what did my wondering eyes behold? A blue egg, about the size of a Jelly Belly. In our male fish bowl.

So will someone please tell me: can a single male Beta lay an egg?

Oh, and no one tell Lucie about caviar.
