Hello everyone new to the forum. I got 2 blue spots for my 150 on thursday. Both dissappeared and then the next morning both had a nice burrow. Both of them ate some mysis last night. I had to leave this morning before my lights came on and both burrows were covered like I know they do. When I got home this afternoon one was out and the other ones burrow was uncovered but never popped out. Should I be worried or do they normally kinda go missing and come back out? I have 200 pounds of rock and 4 to 5 inch sand/puka shell any help yall could give would be appreciated
