Please can anyone help my Gourami's I have had them for a while they have both been in the tank from the beginning and been fit and healthy throughout this time. However I left them for a few days over Christmas and noticed this morning that they both look bloated and seem a little lethargic. The only recent change to the tank has been a holiday feeding 'pyramid' as I wanted them to have food when i was away. I hope someone can advise me on a way to help them. I noticed the GH was a bit high (>21) when i got back so did a 25% change. The below are from the tank after the change.
Tank size: 100l
pH: 6.8-7.2

Fish Symptoms (include full description including lesion, color, location, fish behavior): Both blue Gourami's look bloted as in the picture below
Volume and Frequency of water changes: - weekly 25% changes so far
Chemical Additives or Media in your tank: - I just use the basic water conditioner when i do the changes,
