Heya guys and galls

My Glow-light has developed a lump in the last few and and has today started flicking and scratching it on the plants!

Any ideas of what is it??

possible causes

1) Physical damage. This will normally present as a 'clean' lesion with little inflammation. Usually heals within days. Always a risk of secondary infection.

2) Local tissue irritation caused by ectoparasite infection.

3) Bacterial disease

4) Water quality problem. Test core parameters

5) High levels of organic pollution. Check filters for decomposing solids.
