let me get thie striaght...
You just asked us which species of fish can survive the most torture?
Which species can I burn off their gills, slowly suffocating them, and causing their organs to fail, infections to set in, fins rot off- with ammonia- which one will survive this the longest? that's your question?
FISH CAN NOT LIVE IN A TANK WITH AMMONIA. IT BURNS OFF THEIR GILLS AND THEIR SLIME COAT AND IT MAKES THEM SICK AND SUCEPTABLE TO DISEASE AND INFECTION.
You might as well ask which Dog can I beat the hardest before it dies? What type of rabbit can starve the longest without dying?
Now if you want to know if its possible to keep a fish in a tank with enough plants if you will be devoted to enough water changes with a really really really light bioload- so much so that there won't be detectable ammonia in the tank- then ask that and we might be able to help you.
