I went to lfs yesterday, and picked up two jags and a red devil, all about the same size 3", I paid so damn cheap for them here, $2-3 each;
And so I put them into separate tanks I made, questions : are jags just a carnivorous fish? only reacted them its a feeding time?
I noticed that the red devil is rather smarter compare to oscars and jags. Its the way the fish observing the things around the tank.
Yet, I also saw a bigger RedDevil in the lfs, and when I put my finger in the glass it follows wherever my finger goes. This is the kind of fish I rather have.
I was thinking of buying a GT as well, but dunno much about the fish characteristic.
