Well after doing the two modifications to my Top Fin HOB filter Phil seems to have put on his big boys fins and is being the man. After his light was finally turned off he found a spot to tuck himself in for the night. This morning he is having no difficulty "patrolling" his aquarium and being a jerk to anything he doesn't like. While on his rounds he found a spot right under the filter where he could see his reflection and started flaring at it like a madman until I stuck a piece of white paper there so he can't see himself. His keeper (me) is much relieved.
I think it also helped that he got a couple of his favourite betta pellets this morning.
