I'd first introduce as many XXL sized pigeon blood discus as I could afford, and then later add some says (leopoldi/pearl/motoro) and aros (preferrably Asians) ... and a HUGE school of monster clown loaches of course!
woah nice tank man!
stocking list can be limitless... iwhat i suggest is for u to browse over photos of tanks/fishes online, list those that gets ur attention and what u think would be nice to ur eyes... do a research on the species and finally just let ur imagination play around!
good luck brother looking forward to see pics of ur tanks! cheers!
Wow thats a big tank!!! Theres alot of possiblities with a tank that size. A group of large clown loaches would be cool and a bunch of gold severums ( they have nice color and arent overly aggresive.) Or like someone said a group of red hooks or silver dollars.
