Sigh..sad to say..the male harlequin shrimp of my pair was found motionless today. The male is quite small, only about 1 cm plus. Been doing fine for weeks until today. It was found near the place of my candy cane pistol (Alpheus randalli) which is about the same size as itself.
What is the possibility of the pistol shrimp killing the harlequin shrimp? I can't figure out what else could have killed it as my water parameters are fine and the whole body is intact.
Argh..maybe time to banish the pistol shrimp into my sump. I'll give the male harlequin shrimp till tomorrow. If it does'nt move anymore there goes the pistol shrimp!
