Goby rejected by pistol shrimp?

These posts from my tank thread describe the situation. Thoughts?

12/15/14

My Wheeler's watchman was sold to a local refer leaving the pistol was without his goby partner. In the two weeks since, the remaining hi-fin goby and pistol have been ignoring each other.

 

I had to go out of town unexpectedly for a sad family situation this weekend, just got back home a little after midnight. In the moonlight, i saw the hi-fin hanging out on the sand with the pistol slowly making advances, tapping him with the little claw. Nothing like a witnessing a little inter-species courtship to make you feel better.

I spoke too soon. The morning after the "romance" the hi-fin was looking listless and having trouble centering himself - like his swim bladder was out of balance. He looks slightly "rougher", the way sick fish do when they lose their sheen or slime coating.

 

Has anyone had any experience with pistol shrimp violently rejecting a new goby once their first paired goby is gone? If I didn't know better, I'd say the hi-fin tried to go in the burrow only to be shot with the claw of the pistol and have his swim bladder ruptured. He was swimming, feeding, engaging fine until yesterday.

Is it a tiger pistol shrimp? those guys are pretty violent. I had them before, but I always tried to make sure that the goby was bigger than him. I had a YWMG with a tiger PS with no issues.

It's for sure a Randall's pistol, about 1 1/4" from tip to tail. He was paired with a Wheeler's watchman goby who was bumping up on 2". The hi-fin is about half as wide as the Wheeler's and about 1 1/2" long.

Just a guess but maybe the high find is more timid tha the watchman and being a bit cautious. Or. If the tank has few aggressive inhabitants they may be content. If the goby is eating well should be ok.

He's back to 60% health/normal activity compared to 20% when I posted. So looks like he's on the mend. Wish I had footage of what happened, though.

That happened with my goby he was struck by the pistol and died a few days later I tried to get them to pair for over 3 months and they just never did it

Sorry to hear about that. Violence isn't the answer.

 

Update on my little guy: He's successfully paired with the pistol, so they finally came to terms. He has trouble seeing food on his right side and swims at an angle, so I'm thinking he may be blind in his right eye. I hope they both find enough fulfillment in this relationship to make that sacrafice worth it...
