When I came from a holiday I found only two golden gouramis in the big tank where there should be three. The one who disappeared had a huge blob on his gill but it was getting better. I was looking for him everywhere in the tank - no signs of him. I know he must have died and could have been eaten
but something should have remained?!
Other inhabitants are cories and snails, so they are like cleaners. The automatic feeder worked only once a day in the morning, the fish must have been very hungry! Some plants were eaten too. Otherwise the fish look fine even well fed and happy. Only a bit shy like wildlife species. We also had light switched on for them automatically, but I have a problem with timing on this thing.
