My butterfly is NOT eating.. 8 days and counting.. :( in Disease Diagnosis/ Treatments Posted October 1, 2015 When one of my goldfish had to go into QT, my other goldfish literally stopped eating even though food was dropped in front of his face. I let this happen for four days, then I put him into a large glass measuring cup where he barely could move. He wasn't squashed in the cup, but just couldn't move anywhere other than just turn around and round. I then dropped some food (very very small pieces) into the cup and by just breathing he ate the food because he couldn't escape from the food. I'd try this with bloodworms since minimal chewing is involved (I think) in getting this food into his digestive track. Since your fish is relatively active any flalying around in the cup may result in him swallowing bloodworms. It seems syringe feeding is easier when their energy is lower. If you try this, don't keep him in the cup too long. Will do it in the morning for sure!.. Now.. I've done this in a smaller container (perhaps bigger that what you describing and she in fact swallows some repashy but she spit it out.
