One of the gobies has been found, but no complaints yet that the two spot jumped into the wrong bucket. Hopefully the other 2 gobies will be located, and the tang will find her way home!
Uh oh! Hopefully they get it sorted soon, with a minimum of damage. I wouldn't have expected a sailfin to have an issue with a mono fish, since they're only barely the same shape and nothing at all alike in color. Strange critters.
