My dwarf gouramis always love the bloodworms I put it...although you have to watch not to feed to many of them (I don't think its recommended to feed bloodworms everyday...I did that at first and my dwarfs became bloated...way overfed). Sometimes I put in zuchini (sp?) for plecos and the gouramis love to pick at it...for whatever reason they like to pick at it after its been siting in the tank for a few hours. Usually I will put it in at night before bed, first thing in the morning most of it is still there but then I will check back a few hours later and it will be all gone. Its not a normal thing to feed them but I don't think its bad. I freeze the zuchini (changes the molecule bonds, makes it easier for the fish to chew and digest) and then I cut small chunks off and thaw it with hot water. It floats though...so you need something to hold it down (I have a veggie clip that suctions to the glass).
