Yellow Pyramid Butterfly question

[Stanley-Reefer]

My 3 are fat boys and have grown alot in the 2.5yrs I've had them.

John--do you observe them chasing each other in a spiral motion and/or interlocking their dorsal fins at a 90* angle at dusk? I just wonder if this is a mating dance or a duel:lol:

Purchased some fresh clams...chopped em up and tried to feed the pyramids....no such luck. I'm bummed.....

At this point, I'd try prazipro or an antibiotic like metronidazole... and see if you can clear them of something internal, at which point they may want to eat something.

Have you tried live blackworms? That was the only thing that triggered a feeding response in my Copperband Butterflyfish.
