Need some suggestions.As of late i have not been seeing my lima eating.He use to devour market shrimp and sinking pellets. I can drop the shrimp and pellets right in front of his face and he does not seem interested.All the other fish are eating fine water parameters are all good.Do limas go on hunger strikes like cichlids do at times.Oh yeah he is currently about 12" and other wise seems healthy.Any ideas anybody.
