Hi all, new to this section...I got two venezualan pikes a few weeks ago, around 7.5-8in in size...they were in the tank a the LFS together and stuck together like glue, and up until around 4 days ago they were the same in my tank....but now one is seriously picking on the other, they are doing some major lip locking and the less dominant is spending the whole time hiding! the aggressor also has taken a major dislike to my 7in buttikoferi....and chases him around like mad (really surprised the butti stands for it to be honest!) is this a more male like behavior in pikes? I am considering letting them go to be honest, as my otherwise peaceful set up is starting to get a bit disrupted! and I`d hate for the butti or another of the large residents to retaliate and make a mess of the aggressive Pike!
