Goby and pistol shrimp, where are they?

Question

I bought a pair of a hi fin red banded goby and red banded pistol shrimp yestarday, and the pistol shrimp started to furiously dig threw the whole night, and right away when he got in the tank.

But today, I'm not seeing them anywhere. I don't hear the pistol shrimp snapping either. Should I worry about this?

Thank you!

The goby and the pistol shrimp were ordered by my lfs and they only receive the healthiests specimens available. Their water is so CLEAN.
I fed the tank today also, but they did not come out.
A while ago I saw the pistol shrimps antena, but I haven't seen the goby yet. Just saw his head a couple hours ago.



The goby is the only fish in the tank, its a 3 gallon pico. Tank is around 3-4 months old, and it houses 3 hermits, 3 snails(lots of tiny ones too) and a peppermint shrimp.

Answer 1

The Gobie and the shrimp are probably hiding in the same hole.
Pistol shrimp and some gobies form a symbiotic relationship.
The gobie warns the shrimp of predators and the shrimp shares his food with the gobie.
The shrimp will dig a large cave where they both live.
It's kind of cool.

Answer 2

I once had a pistol shrimp (hitchhiker on a piece of live rock) and I only rarely saw or heard him. He'd snap mostly when I did water changes, and I saw him maybe a dozen times in the three years he was in my tank (usually if a shrimp pellet happened to fall near where he was hiding). If it's new in the tank, it may be a few weeks before you see it again, but I wouldn't worry too much, as long as you don't have anything in the tank that would eat it, and your water quality is fine. (This type of behavior is typical of lots of inverts, where they'll hide for a week or so until they figure out if there's anything dangerous to them in the tank.)

Since the goby is new, I wouldn't worry too much about him either - he's probably still hiding, same as the shrimp.

A quarantine tank is a good idea to keep any new additions in for a few weeks when you first get them. This can be as simple as a plastic storage container or used 10 gallon you can pick up at a yard sale with a small filter and heater with a little substrate and some PVC caves. This will let you know the animals are eating and healthy before you put them in the tank where you might not see them for quite a while (and it prevents diseases, parasites, algae, and nuisance animals (on live rock) from being introduced into your established tank. It's usually easier to medicate in a quarantine, because these typically have less water volume (so less medication is needed) and you don't have to worry about affecting inverts and/or live rock if all you need to treat is a fish.

Answer 3

no.. if something the 1st shrimp is hiding because it would not have this is goby to maintain it feeling risk-free devoid of companion goby the pistol shrimp is amazingly reclusive and additionally you in all hazard wont see it extra suitable than 1x a month

Answer 4

Maybe they just ate each other?
