So, my tank raised clown used to be bullied by another clown. The bullier went missing one day... I searched for days. Then, I found him/her on the floor in the back of the aquarium all dried up. Now, left with 1 clown... He is very timid to this day. He's been by himself for a few months. He always seems to be hiding. While I was rearranging my tank, he decides to go great white on me and attacks my hand. Scares the crap out of me when I'm not ready for it. So, feeding time you'd think he would be assertive. Nope. He hides in the back till I walk away. Then he peeks out looks both ways and then feeds if the coast is clear. What a loon.
