Goldfish have been known to live well past 20 years of age. Koi, can live to see 100 years old.. Putting fish in small tanks and overcrowding with poor filtartion will only shorten the lifespan. The fish may live up to 3-5 years like that, but eventually they will die from their own filth.
I'm sorry if I sound rude, but you're really not adding the right right at the right times. Plecos, or any other type of algea eater, shouldn't be added until algea is on the tank. You're going to have to supplement these little guys with a chunk of zuccini. Also, I'm assuming you just set up the 125.. the tank needs to cycle. I'll be surprised if your plecos make it during that time. I also hope that they are currently in your established tank..
To help the 125 cycle fast, you can add a cup or so of the water from your 30 into that one.
Do you want a semi-aggressive tank? South American Cichlids? You can pretty much do anything you want with the 125gal tank as far as what types of fish your looking for.
