Red serpent star problem

[Rlumenator]

Ophioderma Squamosissimus- I have had over 2 1/2 years- suddenly his body disc has turned lighter, and today I see some white stuff on his body??? Anyone know what is happening?

Have you checked your salinity/SG lately?

The white lesions likely means it's starting to waste away. Is it still eating regularly?
