Copper Banded Butterfly...not visibly eating

Hypo = hyposalinity= lowering the s.g.
HCl can reduce the alkalinity and then the pH so I only zapped four or five at a time.
I tried kalk paste and vinegar before that and they kept coming back.
Quarantine tank allows it to get comfortable after the stress of shipping to the LFS from where it was caught, and, allows for no competition for food so it will eat well over the quarantine period and build up it's strength for the next challenge, to place it in the show tank.
LFS saying not needed but if it dies then you need to make more profit for them by purchasing another one.
