55 Gallon Tank Blue Three-spot Gourami Chasing New Rainbow Fish

HI there!

I’ve had a blue three-spot Gourami for about two years now, and for the most part, he’s been fairly peaceful with other, smaller fish. I wanted to add at least one other fish around his size into my 55 gallon tank. I got a turquoise Rainbow fish yesterday that my Gourami is relentlessness chasing around. There are plenty of caves, plants and hiding places for them to go, but the Gourami has been seeking the new fish out all last night and again today. Is this something that will pass over time once dominance is established, or any trick I should know to stop this? I know Gourami are territorial but it seems like I’ll always be stuck with getting smaller fish because he won’t let another fish his size into the tank.

Thanks in advance!

 

Hopefully the gourami will relax .
Welcome .

 

Who can say? Trichopodus gouramies are a law unto themselves...

Your Rainbow needs to be in a group (6+) so it will be very stressed anyway without the aggression from the gourami. I would expect diseases...

Ah okay! Is a 55 gallon tank big enough to house 6 of them?

Yes.

btw I meant I would expect a strong possibility of the rainbow going downhill if the aggression continued.

 

I forgot the bit about him being ok with smaller fish... so I’m gonna say adding more is a risk. He might bully them all or he might resign himself to them being there...
What probably would work is getting them small...
