As many aquarist know, tanking moving/cleaning can be one of the few opportunities to view a creature normally not visible- like this tiger pistol shrimp.
I do see this shrimp about once every other week. Most of the time instead of seeing it, I “hear” it.
Pistol shrimps can produce a very loud sound much like my mantis shrimp from the past. My wife loves it as it reminds her of the mantis shrimp, which she adored.
This pistol shrimp actually bonded with my fire fish goby and was a master engineer. He had dug an entire subway system in the tank.
My cleaner shrimp began bearing eggs a month after I got them in the tank and I have never seen them without eggs since then. It’s almost impossible to raise young shrimp since they have a rather long planktonic stage. But it sure is a nice feast for all the other critters in the tank when they release the eggs.
Lastly, this nice and big coral banded shrimp has amazing blue marking that is not commonly seen on others. It’s the king of the tank and takes no non-sense.
