Wheelers goby hiding and not eating

[Common Blevil]

Two days ago i bought wheelers goby, that was in the LFS for a while. Accustomed to tanks and eats everything.
In my tank it hides all the time and doesn't eat. Is it a normal behaviour for them? It is not straight from the wild, so i thought it will handle new environment very well...

PS: Few months ago it was sitting with 2 tiger pistol shrimps, but the lfs swapped him with yellow watchman and he was sitting on it's own in the separate tank. Maybe he was stressed without the shrimp and new environment of the new tank did not help? Unfortunately i can't get him shrimp friend right now.

It's normal for it not to eat for the first 2-3 days after being added to your tank, but if it continues after that then something is not right.

I redid the scape to be more stable, so the pistol will not destroy everything and IMMEDIATELY goby started sitting like this in his new cave... It's the first time I'm seeing him like this, so outgoing... I hope he will love his shrimp friend and be more active
