Well I have a 75 gal with live plants....The tank is actually cycling now...Green caorys and red tetras(buenos Aries...I think. I know they are not serpae tetras)
Once tank is cycled
Angels
Black neons
Congoe tetras
Octs
Panda Corys
The only thing I would look for in that setup is whether or not any of those guys are nippy. The angels with those big fins might get picked apart if they are.
I think a large school of congos would make a great display. You could keep a pair of Kribs and/or Nudiceps with them...and a few upside-down catfish(Synodontis nigriventris), synodontis angelicus, or synodontis alberti. This would make a nice West African regional or biotope type aquarium.
I don't really know much about congos, just that they look nice. Some tetras are really bad nippers, like the Serpae are, but I can't say for sure the congos are. You would want to keep a bigger tetra with angels as the Angels are good at eating tiny fish like neons.
Well Losing neons to the angels is no prob. I am a firm believer in the more live the food,the better looking the fish...
What do you think about adding the angels first...letting them adapt to the tank..and then adding the congos as juvies(not too small to be eaten by the angels)
Would this help establish the Angels and prone the congos from nipping????
