What about this for a more reasonable tank - still large, but much more manageable than a very highly-stocked 15,000 or 22,000 gallon tank. It's technically 2, tied into one for a total of 1,600 gallons minus a sump. Both plywood tanks, one of which is 12x4x2.5 and will be fake planted with minimal driftwood, housing:
-2 giant gouramis (1 redtail, 1 albino)
-2 jaguar cichlids
-4 severum cichlids (super reds)
-2 oscars (red tigers)
-4 orinoco peacock bass
-1 banded leporinus
-5 zebra loaches
-25 smaller plecos (5 each: leopard frog, L200, queen arabesque, king tiger, L187B)
-2 widebar datnoids
-6 red hook silver dollars
-2 royal plecos
-1 blue eyed panaque
-1 super red scarlet pleco
-Some bristlenose plecos
-5 bala sharks
-1 Potamotrygon menchacai
-1 Potamotrygon hystrix
-1 Potamotrygon schroederi
Tank 2 is 10x4x2.5, mostly for PBass:
-7 mono pbass
-3 ocellaris pbass
-3 orinoco pbass
-2 hybrid pbass
-1 temensis pbass
-1 kelberi pbass
-1 azul pbass
-2 ornate bichirs
-1 sunshine pleco
-1 royal pleco
-1 black arowana
-1 jaguar cichlid
-1 fire eel
-1 south american lungfish
-2 chainlink motoros
This allows me to keep almost all of the fish I wanted on that list, there are a few that didn't make it (notably the pima and gator gar), and the rays were added in (the main reason I didn't include them in the main tank was because they seem to grow very slow, and I wanted to add them directly to the DT after QT - plus, a tiny $1,000 ray pup won't survive too long in with a big RTC).
