Gumbo

Gumbo the Anglerfish,lures guppies and breeders to the farthest point away from an Alien in your tank by using his luring headlight.Only guppies and breeders that follow him.Carnivore, Starcatcher, Guppycruncher, Beetlemuncher, and Ultravore will not follow him.

Involvements
Gumbo is a anglerfish that drift through the whole tank.When aliens appear, his luring headlight is shining, and he is run away to furthest spot away from that alien and all your guppies and breeders will follow him.That he did have good and bad part :

Good Part
The good part of luring is when he leads all guppies and breeders to the corner away from aliens.

Bad Part
The bad part is if the alien reaches Gumbo's corner, making them all an easy target (Gumbo will move immediately when a Guppy/Breeder is eaten).

In the final boss fight with Cyrax, his headlight flashes just like when he lures guppies, even his ability is disabled for the whole battle.

Story
Many critics of Gumbo say he is a wolf in sheep's clothing...that he simply leads all of your guppies to one spot to make it easier for his alien friends to kill them all.Gumbo answers his critics by pointing out that the aliens have show him no mercy in Tank 5."I am not nor have I ever been a member of the Alien party!"says Gumbo
