Thought i would let you know how Mr. Mellow is doing... and post some pictures of him. He has been in the 100 gal tank for about a week now and has been incredibly mellow hence his name. He does not even bother the fry in the tank. He swims all over and eats what everyone else is eating. I bought special betta food for him but he is not interested in it. No one bothers him and he bothers no one. I do have the 5 gal ready if need be but so far things are working out well. Here are some pictures of him.. sorry they are kinda blurry.
