I mean i know it's gonna be different for each fish but i bought my
yellow tang maybe 2-3 weeks ago and he is still very scared. he'll swima round when i'm on my bed or at my computer but if anyone walks into the room or over to the tank he instantly hides. he doesn't even eat until i walk away. He's definitely come a long way since i first got himn though. I also added a small niger trigger yesterday who still won't come out when anyone is in the room., so i'm just wondering about how long until i can show them off to people haha.
