Anael finally ate a couple of pellets! I had to trick him to get him to try them-- he'd nip at the flakes but spit them out, then try with all other flakes. So I sprinkled some flakes, and dropped a pellet in too. He seemed surprised but he didn't spit it back out. He then had 2 more after the first one! I'm pleased.
I think I'll still be looking out for bloodworms though-- I'm sure it'll make a good snack!
