Yes, very possible for them to go bad over time.

Subject: [RFI] aquarium's fluorescent lamps
Hi,
is it possible that the fluorescent lamps circuitry in my aquarium has
started generating RFI just recently, or did I just never notice it before?
The starter/ballast is a single sealed unit:

With the tubes connected it wipes out from about 1 MHz to 2 MHz, if I remove
the tubes the noise is greatly reduced but still present, and changes from
wideband trash to more of a pulse type.
The tubes used are this type:
