Almost made it to 3 months.
A new addition to the family, a pending move, and a host of other major life changes have put the tank on the back burner. Things have suffered, most notably the nem. During the whole time, the mouth never really closed up tight, so I was always concerned, but overall, it appeared healthy, except for this last week. The nem is starting to fall apart and is hanging on to the rock barely with a small portion of the foot. The perc doesn't seem to want to give up that easily.
It'll be a while before I try another one since the tank will have to be reestablished shortly. Wish I had had the time to carry this one through, but oh well...
