Overstocked 50-gallon

I am fairly new to the hobby and have been at it for about a year and a half now. I started from a 5 gallon to a 10 gallon, up to a 29 gallon and now a 50-gallon breeder tank that's 36 inch x 18 x 19 tall running on a Fluval 306 and a Fluval 206 filter and have overstocked a planted setup with:

2x Sataonoperca Daemon (6 inches each)
3x Geophagus "Red Head Tapajos" (one young adult and the other 2 are 2" juveniles)
1x "Electric Blue" Acara (4 inches)
1x "Firemouth" (4 inches)
2x "Bolivian Rams" (2 inches)
7x "Oto Catfish"
6x "Panda Cory"
4x Syno. "Dwarf Petricola" (cb. have been with me since I had a 10 gallon)

I know some of these fish would not be compatible ideally but I like to try new things out and if they work out great!!! Luckily, this current setup has been going for more than 2 months without any issues, fish look great showing great coloration and my Daemons which are known to be very sensitive to water parameters have been doing great and school with the Red Heads. My Ph sits at a pretty consistent 6.0 while Ammonia and Nitrites have never gone above 0, and Nitrates have occasionally gone up to 5.0 ppm. I do a 25% water change 2x a week. For the time being all has been well and I'll upgrade when needed.

Anyways, i just want to share what I got going and post my first post here.
