ive had a 3" adult red corris wrasse for five weeks in a 20g QT(not realy a true QT it has lots of LR, sand macro algea and choclate chip star)well my 75g was finaly ready and i bought a small 2.5" dogface, i planned on moveing the wrasse and star to the 75 and putting the puffer in the 20g for QT, but when i had the bag floating in the 20g he bit threw it and got out along with the LFS water in the bag, now there both in there and the dogface has ick and cloudy eyes, the wrasse looks fine but i thought i should put them in a larger tank and lower the SG and mabie use copper meds, but the wrasse needs sand and i thought you cant use copper with sand? is copper even a good idea with scaless fish? would upping the temp to 86 or so be a good idea? and most important is i dont have a spong filter or anything just live rock but if i use copper in the QT with rock it will kill it but will hypo kill it as well or just run a bare tank and do WCs? i thought haveing a QT with rock ect would be good for the fish i gess bare is better
