That does look like a sore or injury either from a tankmate or possibly heater burn. Water quality being kept in optimum condition (0 ammonia, 0 nitrite, 20 nitrates or no more than 20 above tap water nitrates level) is crucial and hopefully this will heal in time.

You might find this https://www.fishkeeping.co.uk/modules/ ... sheet.php?caresheetID=125 helpful, in particular about minimum tank size, so it would be worth exploring a tank upgrade.

What are the water hardness readings from the tap? Your water/utility company website may be able to provide specific details of water hardness (CaCO3 or degrees German) for your postcode. This will help us determine whether you need something such as bicarbonate of soda or limestone rock or coral in the filter. The guppies are the fish which may need harder water but the other fish ought to be fine in softer water.
