Feeding Questions

[bugsman]

I have a tendency to overfeed all of our critters and now that I have the saltwater tank everything I read tells me to be careful about overfeeding because it will affect water quality. I have a 28 gallon tank with 2 clownfish, 1 cleaner shrimp, assorted snails, 4 hermits, some zoos, a mushroom and a maze brain coral. I'm sure I've said this somewhere, but the tank has been going since May 21st. I have been feeding 2x per day, flake it the morning, frozen in the evening and it takes them about 5 mins to finish the food or at least look like it's gone. What's the best way to feed? and would it be okay to add another cleaner shrimp or a couple of peppermint fish?? I did my maintenance today, a 2 gallon water change and testing - all my parameters are:
salinity 1.024
ph - 8.1
CA - 380
Phosphate .25
nitrate - 0
ammonia - 0
nitrite - .10
I'm really enjoying the tank and only have a few more things I want to add as time goes on. I'd like to add a firefish and a Watchman Goby and some frogspawn, more zoos and a few more corals. So I want to keep things right and go slow.
Advice appreciated.

With my 24g, I do water chages bi-monthly at 5g a piece. I feed that tank every 3 days heavy (mixture between brine, mysis, spectrum pellets, formula 1&2).My tank a JBJ 24, so it has the back chambers and I feed through the pump to evenly distribute through the tank. I have had a lot of sucess with this tank.
If the purpose of another shrimp is looks, then you would be fine to add pepermints because it would change up the landscape, but either type would be fine in there.
