I agree. Six weeks is the best. It's not like a mandarine, which would die without food, so you really don't have any reason to rush other than impatience. I know it's rough... but just think how happy you AND your fish (all of them) will be when you hit the end of it.
Only thing more dangerous than a 2nd lieutenant saying "In my experience" is a warrant officer saying "Hey guys, check this out!"
