No worries, we are all here to learn more about our finned friends.Right! I've got breeding pairs of Meeki's with zero aggression! Maybe I need to look for the common denominator in the two tanks that possibly set them off.
Anywho, I feel bad for hijacking the OP's thread! Sorry!
Maybe the difference is the near Wild version that TUIC is selling vs tank breed/raised version I have.
I had a wild Andinoacara Rivilatus that attacked anything and everything.
