Semaprochilodus/ Fei Feng

[Xeno]

Hey,
yesterday I've got a new tank.
The dimensions are 200x55x50 (cm) so it's a 550 litre tank.
I'm still planning on the stock.
It will be housing my Polypterus, Mastacembelus and Cochliodon.
In addition to those fish I'd love to keep Semaprochilodus!
But I don't know if the tank is big enough and if it is big enough I do not know if I should keep a single one or a small group.

May not do well with the polys, may suck on their slime coat

Hey,
So they tend to show a similar behaviour to Synodontis?
Years ago my Synodontis eupterus killed a 30cm wildcaught Polypterus senegalus by damaging the slime coat.
