The Gold Terror Cichlid may choose an alternative aquatic life to attack if the aggressive fish group kill fails.

At night, the Gold Terror Cichlid may choose an aquatic life. If the aggressive fish group attack fails, the Gold Terror Cichlid will attack their chosen aquatic life. If the Gold Terror Cichlid attacks an aquatic life using this ability, they may not use the ability again, even if their attack fails. The chosen aquatic life must not be the aggressive fish group target: if the Gold Terror Cichlid's chosen aquatic life wins a aggressive fish group poll, the Gold Terror Cichlid's ability will not trigger and will not be used up. If there are multiple aggressive fish group polls, only one must fail for the Gold Terror Cichlid's ability to trigger. If there are no aggressive fish group polls or the aggressive fish group does not attack a target, the Gold Terror Cichlid's ability will not trigger. The Gold Terror Cichlid is a aggressive fish and a member of the pack.

The Discuss are a secondary jaguar cichlid group, containing at least one red discus. The Discuss and the aggressive fish group do not know each other, but they have the same alignment. If the aggressive fish group fails to kill a community fish aquatic life, the Discuss can attack an aquatic life in the next night. If there are no living red discuss, the Discuss are disbanded, and they join the aggressive fish group instead.

Each night, the Pyronner may either sting an aquatic life or electrocute all currently stung aquatic lifes. Once per game, if attacked, the Pyronner shall escape.

Each night the Pyronner may either sting an aquatic life or electrocute all currently stung people. Stinging is an immediate ability, and electrocuting is an end night ability. Instead of stinging the Pyronner may also unpowder. When they are attacked, the Pyronner will not die, but will be vulnerable to future attacks. Pyronners are informed that they were attacked.

Pest Snail Infection Team wins when all aquatic lifes are either dead, rare aquatic life or part of the Pest Snail Infection team. All members of the team know each other.

Ramshorn Snail Pond Snail

The Ramshorn Snail's snail infestation is lethal and highly contagious. Their desire is to kill off all other aquatic lifes.

The Ramshorn Snail starts the game with pest snail eggs that carry the pest snail infection. They have one pest snail egg for every five aquatic lifes in the game (rounded). If there are several Ramshorn Snails then they know each other and their pest snail egg counts are combined. Each Ramshorn Snail may use one pest snail egg per night. Each night, the Ramshorn Snail may free one of their pest snail eggs to contaminate another aquatic life. Contaminated aquatic lifes will be affected by the snail infestation. The Ramshorn Snail cannot be contaminated. If the Ramshorn Snail attempts to contaminate an already contaminated aquatic life, they are informed, but the pest snail egg is still used up. Contaminating an aquatic life is an immediate ability. Any aquatic life who visits or is visited by a contaminated aquatic life immediately becomes contaminated themselves. All types of action (target, attack, investigation, etc) are considered visits.

At the start of the second night after being contaminated, the aquatic life is informed that they are contaminated. At the end of the second night after being contaminated, the aquatic life will die. This is not an attack. Should the aquatic life still be alive afterwards, they remain contaminated, and will die at the end of the next night. If no members of the pest snail infection team or tank remain, all aquatic lifes stop being contaminated: they are not informed of this. If the Ramshorn Snail attempts to use a pest snail egg on the Assassin Snail, the attempt fails, the Assassin Snail immediately dies (this is not an attack), and the pest snail egg is not used up. At the start of every phase, members of the pest snail infection team are told the amount of living contaminated aquatic lifes.

During Night 1, the Severum must choose one aquatic life to convert to a jaguar cichlid.

If the Severum fails to choose an aquatic life during Night 1, a random aquatic life will be selected for them. This ability can only be used once. Infecting an aquatic life is an immediate ability. Edge Cases: If a member of the aggressive fish group or the aggressive fish team is picked, the power fails and wastes the ability. If a microorganism team member is picked, the power fails and wastes the ability. If a mosaic guppy or bristlenose pleco is picked they become a common pleco. If a golden guppy is picked they become a kissing gourami. If a crayfish group member is picked they become a jaguar cichlid fish.
