So I bought a new flame gouromi today to be buds with my blue dwarf gouromi that my girlfriend gave me for my tank. I'm almost certain that the one I already have is a female because you the rust colored stripes are very faint. The flame dwarf gouromi is for sure a male. I expected that I might have to get another female because the male might pick on the female. Now, here is what is strange. I put the flame gouromi in the tank and the blue female attacked it constantly. The blue female is a little bigger than the male and this is the only reason for this i could think of. Is this just normal and will it subside or i'm i going to have to get take back one or the other? I'm rather confused.
My Tank:
20 Long
4 zebra danios
blue dwarf gouromi
red flame dwarf gouromi
Thanks for any ideas
