He became a Bit Aggresive lately, i never seen him like this before.... i throw in 2-3 Disks every night, i have 3 pleco's and it's just recently that he became soo Aggresive.... I don't know what to do......

Also, my Clown fish keeps getting himself stuck in a small hole........ i mean he can get out of it, but i'm not sure if it's ok.....
