fish acting funny but no visable signs, suggestions.

[sparky101]

ok heres what I have
46g Bow
60lbs sand
40lbs lr
1 coral beauty
1 sixline wrasse (added yesterday)
1 longnose hawk
magnum350 canister w/ carbon for filtration
2 p.heads
ph steady - 7.8
amm.-0
nitrite- 0
nitrate- 20
I got the wrasse yesterday (4/22) from lfs. he was there since tuesday (4/19) and looked ok. today I noticed my coral beauty was swiming funny. he scrapes himself along the heater and ocassionaly twitches and darts around. although i did notice him scraping himself when he had a big turd hanging, thought he was trying to get it off. my hawkfish has also been twitching ocassionaly.
Could this be early signs of ick? the wrasse seems to act normal and none of the fish have visable signs of anything.
Any suggestions would be appreciated.

Yes.
Heavy feeding with freshly minced garlic, perserving the juices for soaking in meaty foods to be given to the fish, several times a day.
