Most of the crew here feed everyother day. I feed everyother day and about every two weeks I'll skip a scheduled feeding. The polys and rope are more active on a feeding schedule like this seems counter intuitive but seems to work for me.
Now that's a story that we want to hear.I presume she is passing everything fine and not acting weird? If she is acting normal, then I think you might just want to cut down on the feeding (IMO, I don't have much personal experience with bichirs aside from holding onto one for a friend when his house caught fire)
If parasites are involved I doubt the fish would get so big in a captive setting, and catching a fish to make it eat may well put the appetite off.Could she have parasites that makes her really hungry? I think feeding her on her own would be better to make sure she only gets a certain amount, or feed very slowly so she can't reach the other foods?
In the wild these guys can often go weeks or months with out food depending on the season. They do a funny thing where they cram food into their body. If they do this on a daily basis it can definitely cause obesity which would never be good. Lots of people need to monitor the diets of their polys to make sure they don’t over eat. Some times what I do is I feed floating pellets to my other fish so the poly will miss out a few days a week on food.
