I can't comment on the eel, I've never had one, but the clowns will eat just about anything and stay healthy; they're omnivours. You could pick up a small container of flake food, mysis, and maybe some other type of frozen food like Emerald Entree, and they'd be happy. You could even use Cyclop-eeze, my clowns go crazy for that stuff too.
Like I said, a variety will keep your fish much healthier in the long run.
Also, a though occurred to me on the pH issue... do you have a glass lid or some other type of solid covering on the top of your tank? If so, this might be a part of the low pH. Gas exchange from having an open top can definitely help keep pH much more stable and help it stay at the better level. If you have a glass lid try swapping it out for egg-crate (lighting diffuser). That might help.
