So I have a small YWG paired with a small pistol shrimp, they were a little skittish, but saw them frequently, I added a cleaner shrimp and the goby hasnt came out of their burrow at feeding time anymore, If I uncover the burrows door, and leave some pellets the shrimp will pop out and grab them, but hoped my goby didnt die, after 3 days MIA I sucked up the substrate covering the burrow entrance, and a few minutes later the goby popped out! I got some food to him, but the second he saw the shrimp he shot back in and they covered the entrance again, will the shrimp bring him pellets? Is there any way to encourage him to come out more?
