I added a pistol shrimp and yellow watchman goby pair to my tank on Friday morning. I drip acclimated them for 2.5 hours. When I added them to the tank, the pistol shrimp immediately darted for the rocks, and I haven't seen him since. The goby headed for the corner of the tank and sat there for about 2 hours without moving much at all. A few times just before going to bed on Friday I noticed the goby moving from rock to rock, but still staying where I could see him. When I woke up on Saturday there was no sign of either and I haven't seen them since. I also haven't heard any clicking from the pistol shrimp at all.

I know some fish are scared and hide in the rocks for days if not weeks after they're added, but every fish I've added so far stays out in the open right away and seem happy. Every shrimp I've added to the tank has molted the same day I've added them, so they hide for a few days until I see them. I'm just worried because this is the longest I've gone without seeing my new additions.

Fellow tank mates are 2 small false clowns, 1 firefish, 1 royal gramma, 2 cleaner shrimp, 1 peppermint shrimp, a few hermits, and a few snails.

Should I have at least heard a click from the pistol shrimp by now?

Thanks.

Generally you want to release them in the same part of the tank so they can find each other as fast as possible. Once they do, you won't see much of them. The shrimp noises are mostly nocternal so you will probably be asleep for the.

The pistol shrimp and goby pair will live together in a burrow and you will not see much of them except perhaps at feeding time. But you will know they are there as they will mess your sand up pretty bad.

I have a black ray goby and pistol shimp pair as well. They were paired at the fish store so I released them at the same time. Current was low at the time. After thinking about it, I am ****ed lucky that they took up a burrow right in the front of the tank! I could easily see where they could disappear into the rocks and only be seen at feeding time. Keep an eye out for disturbed sand and toss a few pellets in there down near the bottom and see if they come out.

One trick for mine is to put a cube of reef food in the tank first, which gets eveyone excited. Then once they are all fired up I put in the fish food. That seems to be a good way to get everyone out in the open for inspection.

It's now been a full week and still no sign at all of either one of them. A few days ago I thought for sure I found them. My peppermint shrimp used the exact same spot as it's home for over a month now, but decided to move to the other side of the tank to a new hole in the rocks. The area where he used to hide is now overrun with sand and there's a new burrow looking area a few inches away where the sand and rock meet. I shined a flashlight in the hole many times now and I can see the back of the hole with no critters in there.

Do you ever hear a snapping noise coming from the tank? We added the same pair to our tank months ago. We lost the goby, but the pistol shrimp has thrived. We never saw him only heard the snapping noise from time to time which let us know he was ok. I know he is there though because sometimes when we get up in the morning you would think some heavy duty bulldozers had been working overnight. The sand is all pushed around into mounds with deep crevices around the rocks. He does now appear from time to time when we are feeding the fish. Be patient, I am betting he is ok.

No clicking at all. There are strange mounds of sand around the rocks. If I try to add another goby but the shrimp ends up being gone too, will the goby be ok alone? Will he just hide all the time?

The goby will be fine alone. It's the shrimp that really needs the relationship.

The mounds indicate the shrimp is alive. Make sure the goby is gone before you an another watchman, they might fight a bit if you put in another and the one is still alive.

I seldom see my goby and shrimp either one. They are kind of an introduce them and forget them kind of couple.

I had completely given up on either of them being alive in my tank since it's been a month and a half since I've seen either one of them. Yesterday when I was feeding everyone, out of the corner of my eye I see a quick flash of something. I dropped more food in that area and patiently waited for a few minutes and out pops the pistol shrimp. He grabbed the food and very quickly retreated. So now it looks like I have the shrimp but not the goby.

I was planning on adding another fish this week anyway, so I guess it will be a watchman. I'm pretty sure the pistol shrimp is a tiger pistol. My LFS always has a nice selection of yellow watchman gobies, but they do occasionally get more exotic watchman choices. I've been trying to find a list of compatible pairs, but I can't find one. Any ideas what other varieties are compatible with the tiger pistol shrimp?

Mine did the EXACT same thing, they paired up within a day or so and their hole entrance was behind the rock work, eventually they made the hole at the front of an adjacent rock and now the goby is out when the lights are on, pistol shrimp comes out quite a bit too, always moving sand and seems to decorate the entrace with shells heh

Didn't hear clicks until week 1 or 2, now hear them during the day and night

I bought a yellow watchman last night. The LFS had them on sale for $6.99. Can't beat that. The next cheapest watchman was $35.

Yeah I know about the mantis shrimp. I really like the colors. but, don't want have to deal with broken glass everywhere.

I was just curious. I watch a youtube video of a pistol shrimp attacking and eating a cleaner shrimp. So I figured I would ask if that is a common thing to happen.
