I'm actually a little worried that he's damaging his mouth by hitting it on the side of the tank constantly. Is this a common stress response for butterflies?
I suppose it's possible but since he's been doing that for five days I'd still be worried. My other idea is that maybe the tank is really bright for him. They don't have much lighting on the tanks in the store and I have 2x250w MH. He is in the darkest part of the tank. But now he's really not eating well so that just concerns me more. I'm gonna get some food when I go into work today and we'll try a few different things.Could it be seeing its reflection in the glass and going after the reflection? This is common for fish new to a tank if they see their reflection (frequently, from light outside the tank). My cbb is chasing its reflection in the QT right now.
drew,
a tinker's butterfly behaves exactly like declivis, burgess and mitratus butterfly. reefsafe wise that is. they all are extremely hardy and will feed with no problem.
as for reefsafeness, they are a hit or miss thing, like dwarf angels, but i have tons of success with my very own mitratus and declivis.
