I have 4 gouramis 2 opaline and 2 pearl.
They seem to be peaceful to each other so far but this morning a piece of one of the pearl back fins got ''i think eated'' like 1mm
What should I do to prevent the fish from killing each other D:?
i have a 150gallon tank plenti of space for these fish D: ( 72'' 18'' 28'' )
I have worked me filter with ammoniac for 4 days ( 3 filter ) and some bubble maker O2 i think. The aquarium is planted but theres still a lot of open space.

Thank you

At feeding everyone seems happy and all
but 10 minutes after the 2 pearl gourami ''fights''
they touch each other with there lace then go face to face then one of them rub the other body and they turn around like circle.
Are they playing or fighting ? What should I do? they are still only 1-2 inch

Sorry i am new in this forum i just added the info that i could fill. I have added some barbs today and now the gourami seems more peaceful o_o. I wonder if they will start refighting >.<.

Thanks !

Hi Gouramis start to be more aggressive when they grow. You need to remove open space and replace with a lot of live or fake plants so they can hide and dissapear from others gouramis. hope it will help!
