if he has very hard water their how do you reccomend maintianing soft water.i am very curious myself?? ro

Peat, Indian Almond leaf extract(Ketapan leaf) I've even used some kinds of tea.

Just a little will do, which leaches into the water slowly. A minor drop of PH over time will not harm the ray.

It has a staining effect and might affect the whiteness of black & white based rays but there are beneficial minerals to counter this too which I would go into detail.

My rays sometimes gets these white spots on their disc when i do bigger water changes. Other times they seem to get it when the nitrate exceed 30ppm... or when they are being bullied by another ray.

So i have concluded that the reason must be stress.
When this have occurred i have never seen any loss in appetite though... nor any changes in behavior.
