dragon goby agression?

  • We are currently upgrading MFK. thanks! -neo
How large and how old are they? How large is the tank?
I've seen video and read about them fighting. It's pretty nasty.
It could be that your gobies are immature. Maybe your tank is actually large enough for them to each have enough space. I suppose that if you were lucky enough to end up with two females, they might not show much aggression, but I don't know for sure.
 
I agree, probably age and/or more than adequate space. I only have one but he has gotten noticeably more territorial and rarely explores the caves he didn't choose as his to defend anymore. He used to be a little more adventurous but now he stays almost exclusively in his chosen side of the tank.
