Love, love this tank... the West African Riverine is my next build AfricanUpdate Video
so I was happy to find your thread.
Couple of questions:
I see that the one tetra is phenocogrammus interruptus, but the other am not sure about--- is it brycinus longgipinnis? It is defiantly better for these larger tetras to go into a longer tank, you can really see their interesting shoaling behaviors.
What filter do you have on the tank, any power heads to increase flow, or find not necessary?
