Hi guys yes that's what the neons had
1.Restlessness.
2.Fish begins to lose colouration.
3.As cysts develop, the body may become lumpy.
4.Fish has difficulty swimming.
5.In advanced cases the spine may become curved.
6.Secondary infections such as fin rot and bloating.
I ask the shop and they think it was columnaris any way it affected my glow light tetras and they died is well I did notice blotting and fin rot and coloration.
guys you reckon it's neon fish disease or columnaris .
