The Pinktail is my favorite.
He isn't aggressive, but he doesn't take any sh*# from the Undy. The Picasso is in his own little world.
The Pink and Picasso were introduced at the same time, then a couple months later, the Undy. The Undy and Pink went at it a couple of times, with Pink winning. The Undy kind of chases the Picasso once in a while, one length of the tank and then she runs and hides.
They are very different. The Picasso is always at the top of the tank, the Undy on the bottom, moving from cave to cave, and the Pink goes where ever he feels like.
Thanx for the compliments, they are great fish (Undy included
)
