Hey guys i got a problem i think. My yasha hase is out in the open swimming near the top of the tank. this is very unlike him. i have had him for about 9 months and he has never done this. i covered all the openings with thick layers of paper towel so he doesn't jump out. i also turned the lights off about an hour early to give him some cover. my tomini tang is being a ultra A$$ to him. ideas? about 3 days ago i rearranged my rock work. maybe i accidentally smashed my pistol shrimp? i was careful not to mess with the rock they normally come out of when i feed the tank. would that cause him to leave the burrow? yesterday i added a pair of black ocellaris clowns, but they are very laid back. i haven't seen them do anything aggressive. Any help would be greatly appreciated!!
