alright i'm leaving town for about a month for boot camp. during this time my roomate and i are moving into a different apartment. i have a 55g tank with a skunk clown, 6-line wrasse, firefish, cleaner shrimp, pep shrimp, and about 3 hermits. to make his life easier i was think of cycling a 20 long i have laying around and have those fish in there for the month i'm gone. i would of course have what live rock i don't use in the 55 partly full with some powerheads. my roomate has been with me and helped me set up the tank so i'm not worried about that. i'm worried if the roughly 30 days the fish are in the 20 long, will they be alright.
