Hey there everyone. New to this forum and I was hoping I could maybe get some help with my poorly make red jewel. He is one of a breeding pair. He has been showing some white patches and losing colour for about 3 months now but it usually only lasts a few days before he's back to his normal colour and then comes back a few weeks later but always seems well side from the colour. But this time it's been going on about 2 weeks and he seems very lethargic and off his food. The rest of the tank seems fine not displaying any symptoms. I've tried all the usual treatments , anti internal, anti fungal, salt, water changes all to no avail. Have included photos. If any one has any ideas please let me know. Thanks in advance
