200 Gallon stocking question

[Krisg19]

Hi

So with my new tank arriving within a few weeks im looking to build my stock list currently to go in the 200
Fish i already have (Will be staying in the aquariums they are in till the 200 is up and cycled):
4 Ctenopoma acutirostre
polypterus ornatipinnis
polypterus ansorgii

I am looking at adding a synodontis longirostris would the be any issues with this and also looking for some other suggestions of what would be compatible.

 

[twentyleagues]

Other lower jaw polys or upper big 3 weeksi, teugelsi, other larger synos. Just make sure the synos are to big to eat when introduced. Most grow fast but can cause a choking hazard for fish trying to eat them.

Really i only wanted to keep with the one syno listed above as finding a longirostris in the UK seems to be becoming a task more polys would have been an idea but the only other poly i want is a polypterus teugelsi but been unable to find. im looking for some suggestions on dither fish or some other African based fish that maybe easy to find. I was thinking a Xenomystus nigri but due to the maximum size and body shape think it might become a spaghetti string for the polys.
