Tank looks great man, and congrats on the new baby girl!
Your tank has gone thru so many changes! I would suggest getting some turquoise rainbows, to add some deep blue color to the tank. I just recently added rainbows to my 90g also. You have at least one female in there right? As you probably know the males show colors better when there is at least one female in the mix of things.
The baby plecos were and are extra cool, especially to have a spawn in your tank like that. If you are looking to get more angels I'd look to aquabid.com or even ebay, as some good breeders can be found there that are relatively local, (US based).
That java fern you grew out was amazing! Your plants seem to do quite well. I bet it's the co2 and the good lighting. I could never get my ferns to grow that much in the period of time you showed in the pics. My tank is low tech though, so there you have it.
You weren't using Prime all the time to remove the chloramine? I just buy a big bottle of it off ebay for around 58$ shipped, and I'm good for a couple years, for my 90g and my 125g.
One more thing, the wood addition was and is a great addition to an already great setup. Keep on growing those plants, and fish!
