when you feed them bloodworm, do you chop them up at all? The worms seem quite large compared to my neons!
I have had my neons for 15 months now so I daresay they are about as big as they are going to get. They may be quite a bit larger than yours if they are only young.
I just put the bloodworm in as they are and they love them. I keep frozen bloodworm all the time but they like live bloodworm even better so when I am passing the LFS I often pick some up for them.
