N0body Of The Goat
Oddball and African riverine fish keeper
A riverine loach group (eg. Dwarf Chain) or catfish (singleton to 5 depending upon species, eg. Hoplos with their sturdy armour; or Synodontis spp.) might work. Another possiblity would be a group of 4 or 5 Panda Garras or even BN Catfish, who both love current.
Suggestions would come down to whether you want this addition to be a diurnal species or whether something nocturnal would not bother you (and hopefully not spook the SAPs who I believe huddle up together on the tank floor).
