Another QT question.

[reefbound]

i just picked up a Sixline that my wife fell in love with and my daughter named it dora-thy, and thats how she says it (she really understands that we cant have a Dory in our tank because she gets too big) so she's pretending its Dory... Anyway to my question.
My Qt is a 20 gal long with a millenium 1000 wet/dry filter and the Sixline is about an 1 1/2 long, just a little guy, how much water should be changed and how often?
I was thinking 5 gal a week or should it be a gallon a day?

any thought's would be helpful. Is there anything that can be done to help his fins along,Looks like hes been picked on at the LFS.

A gallon a day would be good but you need to check the water level to be sure. More may be necessary. You need to maintain pH, and keep ammonia and nitrite at 0 and nitrate as low as possible.
