Frag Tanks... Fish or No

[Mr_Banana_Pants]

I was looking for some opinions on whether I should introduce any fish into my new frag tank. My last frag tank had become overrun with algae due to me going on vacation and having to use an automatic feeder... I'd prefer to not break this tank down again, too exhausting to do this again. Thoughts?

I personally have my frag tank as part of the system and yes usually have a few fish, usually the aggressive ones towards other tank mates.
