I think I may have just answered this in response to your last post,
before reading this post.

AFAIK, DOW Chemical owns the brand name Styrofoam, whose trade name is
polystyrene. Dow (and others) makes both expanded and extruded
polystyrene. Expanded polystyrene (usually a white material made up of
many little bubbles, used for packaging) is more compressable and comes
apart more easily than extruded polystyrene (usually has a very smooth
skin and when opened, has the texture of a chocolate Aero bar).

It becomes somewhat impractical (I think) to ensure that every paint or
dye is inert (fish-safe), so I rely on sealing it, under Fiberglass or 2
part epoxy.

You did thanx. I'm off to look for extruded polystyrene suppliers in the
UK.

The 2 part epoxy works great (by the way, a place that sells boat or canoe
kits will sell it). To be extra safe, when i made my styrofoam stuff, I
used non-toxic water based paint. In any case, most of the guides should
tell you to stay away from acetone based paints as they will destroy the
styrofoam.
Good Luck
