That setup is the bomb - loving the blood parrots. They are so vibrant red - what do you feed them? Hai Feng pellets?
Your RTG's are amazing - wish they were affordable here in Australia. They sell for $3000 at 15cm.
If money wasnt an object i'd replicate the same in my sump but only on a smaller scale. Fish in the last compartment, that's hilarious!
I will be keeping an eye out on this thread, great job and keep updating with pics and more info as you go. You can teach alot of beginners a few things here including myself!
