So I bought a yellow assessor 12 days ago from J&L. During the first 4 days I saw him a total of 15 min, even bribing it with food did not bring the fish out of hiding. On the 6th day I started moving rocks in an attempt to find him which i did for 5 seconds, but now he is hiding in another hole (at least i hope so). My parameters are fine, there were no other fish in the tank until 2 days ago i added a clown. I dont know what to do now, should i go back in and look for him, or just write him off since i know he is not eating any food i put in the tank?
