Brought two more new fishes yesterday but think Fartface is either very hungry or very territorial having the whole tank to himself for a couple weeks now. He keeps chasing the new fishes with his mouth opened. I kept a close eye last nite making sure that noone dies. poor things. and like a mother i even shouted, "No fighting!" sigh.

This morning i fed them but Fartface ate ALL the food. the new guys must still be scared or s/t. anyways, i also can't help to noticed that i either got really small fishes or that Fartface got really big. He looks like a giant in comparison.

Anyways, if the fishes are still butting heads i am going to return one of them.

Question: is this chasing normal? and can one little fish survive in a pasta sauce jar??
