I'm not tired of keeping Tetras. I'm tired of scooping their carcasses out of the tank
I may try adding a trio of flying foxes and maybe a couple denasonii barbs - in the hopes that's they may get large enough, or be fast enough to elude the GT's.
But here's why I am torn on that... since loosing my last flying fox (SAE) my tank has grown a nice lush blanket of hair Algae on a lot of the wood/rocks. It doesn't look the nicest, but I always see the fry feeding off it. I don't know if they eat the Algae specifically or the detritus that gets trapped in it (I suspect the latter). This is a good thing because I don't feed the fry, I just feed the tank like normal.
As far as cichlids go I was thinking it will either have to be tough/smart, or look different enough that the GT's ignore it.
So I was thinking maybe a male convict or two (tough/smart), or perhaps either a dwarf pike or Geophagus Steindachneri.
They each have their cons:
Convicts: not from same continent.
Pike: will eat fry relentlessly.
Steinies: may be too similar in shape. And while Steinies are hardy for Geos, they wouldn't stand a chance against a GT (most likely).
