I have a problem in my low tech, planted Juwel Lido 200litre community tank. Been established with quite light fish load for 18 months with no losses now neons are losing condition one by one, I had 16 now have 10 or 11. The sickly ones show one at a time, emaciated, fins twitching and I have been euthanising when they appear terminal but nothing else obvious? Fish are same age as the tank. No fin rot or bumps, bulges, lesions etc. Other fish appear unaffected (Honey gourami, corydoras) although I have lost (literally) my fairly new female apisto borelli and One of four honey gouramis n the last 3 months which is quite high mortality.
Water is as soft as it comes, temp 24, 50 litre w/c weekly. Zero ammonia, nitrite. Possibilities, treatments appreciated.
Sickly fish and a healthy one below
Thanks
