Hi Mariah, yes - goldies can eat bloodworms. They are high in protein and as you say can promote growth, particularly wen growth but that doesn't mean you can't give them to wenless fish - they will enjoy them just as much and will be just as beneficial as a dietry supplement. Freeze dried, frozen or gel form are all good. Bloodworms also have a slight laxative effect on fish so can help to prevent constipation/swimbladder problems
