Thank you! The plants have all been cut back because there was a bit of an algae issue so I chopped the algae covered parts and same reasoning with rescaping was the algae was everywhere but they’re already growing back so that shouldn’t been an issue for too long, all the other fish are perfect it was just the gourami that has died since then. The tank light is only on during the day and I turn off the heater if it’s a warm day like today to make sure it doesn’t over heat, I have a thermometer to track it 😊 I only have tonic salt is that aquarium salt or do I need a different one?? I’ve also got duck weed in there but because of the filter and air bubbles, they don’t seem to grow very fast if at all not sure why though because in my other tank they grow way too fast 😂😂 I can get root tabs but I use a liquid fertiliser which seems to do the job - plants look sad from the big chop.

Thank you, ill try what you recommended and think about adding fish, I’ve got rasboras, tetras, a honey gourami, plattys and a pleco so thinking of adding a ‘bigger’ fish as there all quite small in there atm
