I have not tried for long term staining worms, but for larger species, the
fluorescent elastomers used in amphibians might work nicely. The are
injected under the skin with a syringe, and tend to stay in place and be
visible through the epidermis, so you can combine color dots to achieve
group or even individual labeling schemes.

Cheers!
