Stocking?

[ViolentJ]

This year I intend to get rid of my glass tank and move to an indoor pond. It will be 6' long x 4' wide x 2' deep and hold 1300 litres / 343 US gallons.

I currently have the following fish:

Tiger Oscar
Gold Spot Sailfin Plec
4 Silver Dollars
Ornatipinnis Polypterus
Sengalus Polypterus
2 Delhezi Polypterus

Ideally I'd like to keep these fish and add some new ones but I'd not really sure what I could add. Obviously a few more silver dollars would be ok. My Oscar is tolerant of other fish as long as they're not Cichlids. Whether this would change in a bigger space I'm not sure.

What do you think my options are either with the current fish or a complete change.

i'd say double the school of SDs and you'd be pretty well stocked with a little more room, though i'd get rid of that pleco, sometimes they go after polypterus and suck off the slime coat which can kill ur polys, at that point i think you'd have plenty of room to get either another school of something or some other mid sized fish. If it were me personally I'd add more bichirs, perhaps endlichiri
