Pistol/YW Goby Hiding

[Cal_stir]

we have a pistol shrimp and had a orange spot goby, they would sometimes hide for days at a time, then the goby got ick and died, the pistol never came out for a month or so, we couldn't find it and thought it had died, then we got a YWG and they hooked up in a couple hours and the pistol came out to our relief, then they disappeared for a few days and now they are out a lot but once in a while they disappear for a day or two, so I wouldn't worry, it's normal.
