I only named one, and he's now dead. My leopard wrasse named Houdini.
Houdini was great at vanishing acts. When I switched from my 29g to a 60g, he buried himself in the sand. Everything was out of the tank and I sifted through the sand completely, and no fish. The next morning, there he was swimming around wondering what happened to all the rock.
He was later moved to the 100g, where he was fine for a long time. Then one day, he performed his last trick. Disappeared, and did not reappear for a few weeks. When he did, it was with a swarm of hermits devouring his carcass.
I decided not to name any more of my fish after that.
