Rissan bleeder fish

Introduced on the Taisidon safari events in the Coral Reef shop, the note by the fishbowls for sale reads:

"Announcing the rare Rissan bleeder fish! This fish is so named because it squirts a dark red ink when attacked which gives the water around it the tint and consistency of blood. The attacker is usually fooled into thinking it caught the fish, and therefore doesn't go after it as the bleeder fish escapes. Be the first in your neighborhood to have your very own pet bleeder!"

OOC Reference

For many years, the most common method of training First Aid was to keep an area on your body bleeding that you could continue to tend repeatedly as you kept the wound for an extended amount of time. Over time, the player base started calling these pet bleeders. The reference to this in the shop is a tongue-in-cheek acknowledgement of this phrase.
