tetras would make good feeder fishes too, no ? ... 
Tetras won't last 5 mins in my tank
My fish are excellent predators
The other time someone told me if I poured in 20 bucks worth of
catfish, I will get to see them biting the stingrays
Satan Gal replied on my behalf that in my tank, I pour in 30
bucks of catfish and they are gone in less than 20 mins :P
