I had the six line in my 120 to rid it of bristle worms and he/she was fantastic. It would charge at other inhabitants on occasion but never any harm done. It was painful finding it stuck in mesh and couldn't be saved.
Re: fish in frag tank - I don't think so with it so shallow and topless.
My other 2 tanks are pretty much on cruise control. Both are monitored off a single Apex and I spend maybe just over an hour per Sunday testing, cleaning skimmers, cleaning ATO sensors, filling ATOs and cleaning glass. It's pretty much routine these days. Both are on dosers and auto feeders so during the week I just sit back and enjoy them.
