ESLOW--
You and me both love the puffers. I have a stars and stripes ordered. A HUGE one.
But, I think I did get lucky with my Clown Trigger. This dang fish is about 10 inches long, about 2 inches wide. I grew him from 7 inches. I got him for 75 bucks when I worked at an LFS. I've had him for about two and a half years now.
He has his moments. Sometimes he swims full blast from one end of the tank to the other... and pushes everything else out of the way.
He has made me bleed before. He knows the taste of blood now.
But, let's see..... he HATES any wrasses. He has killed two Harlequin Tusks smaller than him. And a lunare wrasse. OH MAN... he beat the hell out of that thing before it died. Huge holed in it. It lived under a rock for a month and almost healed but he took care of it when it emerged.
I sump him when I add ANYTHING new. Clowns are my favorite fish ever... so I refuse to not have one.
But, it has just been an expensive trial and error on what I can add with him. He respects my nurse shark so far.
I think it's because they don't eat the same food.
My huge Sohal tang that just got devoured by my huge tesselata eel.... they flared up at each other sometimes. But they were pretty cool together. As long as I keep him well fed... he is pretty laid back.
Beware though... they are devious, sly fish. They're smarter than people think.
