I think the carp you mentioned above is kind of linked to the Koi type application Rod mentioned. Grimes uses goldfish for this as they don't get as big, slow moving, and are brightly colored / easy to see.
- Would need to do the research on it though. Not sure if they would muddy the water, or what it would take for them to spawn if they would spawn.

Good luck on the search and the research.
