I'm helping a friend re-do a tank. I'm pretty sure she has a pair of pacu in the tank, and she's lost several small fish over the past year. F'rinstance, she bought a dozen neons two months ago, and now there's just one. Will pacu eat smaller fish? If so, why would one neon survive for two months? Or, should I be looking for other reasons for her inability to keep smaller fish?
Thanks,
Val
