So I have had my Royal Gramma in my 32 gallon biocube for about a year now and it has been great. For the first few weeks after I added it it spend most of the time hiding in my rocks only coming out to eat which I know is normal because they like to hang in caves in the rock work. After the first few weeks I rarely would ever see it hiding, it was always right out in the front of the tank which was great to see. I am worried because I have not seen it for about 2 days now not even during feeding. I noticed about a week ago he began hiding in a hole for most of the day but I saw it poke its head out periodically. The last 2 days on the other hand I have not seen it at all and am beginning to worry it is stuck in the rock work or something, anyone have any ideas.?
