Does live foods raise aggression?

  • We are currently upgrading MFK. thanks! -neo
I've heard this theory for many years... throughout many years of keeping Cichlids I've never found it to be true...

Right now I'm breeding a lot of fish, but not doing much with the offspring. 95+% pf them end up food for other fish, most of those are raised to the 1/2~2" before doing so... In other words I have a lot of fish that eat young Cichlids as feeders very regularly.

I've found this tends to make them more aggressive feeders... meaning that when food is put in the tank they aggressively dart to the surface to see if there is any live food... but after that moment they are just like normal...
 
I've never noticed this supposed increase in aggression due to feeders, although I'd refrain from store bought feeders for numerous other reasons.
 
The Pbass I used to have would be snapping at anything a couple days after a feeder session. And they would usually be pretty calm for the most part until feeding time.
 
I've never had fish get more aggressive twords other fish due to live feeders when live foods are placed in the tank my fish sure do get moveing so it makes them more aggressive feeders but not more aggressive twords other fish
 
I have heard this before but it hasn't happened IME.
 
This might sound funny, but I use this as a training method to keep my fish net friendly. Ive fully trained my pike to swim into my net, because I feed him live food out of the net. My Jaguar is quickly catching on . Then for if for any reason they have to caught and tank swapped or something your not chasing a fish in a 150 tall where you cant reach the bottom..
