I bought a royal gramma 2 weeks and he has been in the QT. I have a piece of live rock in the tank and he hides and does not come out. I see him when i turn the corner to the room then he darts to the rock. I do not want to stress him out but i want him to get used to seeing people and not run and hide. Because it can be kinda hard to see if he has any issue when i can never see him. I thought about removing the rock and putting some pvc pipes in there so i can see him better. Please let me know what you guys think and tanks for the advice.
