Actually I took more like a 30 year break from the hobby and have been amazed at all of the cool fish/shrimp that have either been discovered/developed in that time frame.
Very similar situation for me. I took a good 20+ year break and when I started to do research to come back it was interesting that under gravel filters were out and that there were some really cool cichlids now available (flowerhorns)
So I buy a 65B I find used on Craigslist and then the addiction starts and I now end up with a 300g, lol
