I have had three dwarf gouranmi for about two years now. No issue at all with the shrimp. I quarantined the gourami for about 5 weeks before putting them into the main tank and haven’t had any issues since. I started with 6 cherry shrimp and they have happily bred and ther are now so many i have spread some around into other tanks and even given some away to friends. Also have CPDs (my favourite fish) black neons, embers and chilli rasbora in the tank.
