Guppies become colorful which is bad because it attracts predators so the more bright and colorful a colony is the less amount of Guppies are going to be there. If they are drab then there are going to be hardly any bright guppies and only the drab ones. Coloration would be from the guppies trying to adapt to survive get the drabbest color they can be in order to survive so the predators influence is going to be there are going to be a high amount guppies in a colony if it has for example 30 Rivulus. But if they're more types of predators like Acara's and Cichlid's they're going to be no bright guppies only drab.

Variation in guppy coloration developed as a trait due to sexual selection. Female guppies prefer males with brighter and more colorful patterns, leading to the evolution of diverse coloration in males as a way to attract mates. This color variability helps males stand out and successfully reproduce.
They have disruptive coloration.
The parents or grandparents of these fry probably has (or had) the same coloration.
Aposematic coloration (also known as warning coloration) is the conspicuous coloration of some animals, such as skunks and poison arrow frogs, that serves to warn potential predators of the harm that would come from eating the animal.
A Neon Blue Guppy doesn't really defend its self it usually hides.
Camouflage
Assassin bugs are red and black in coloration as a form of warning to predators, signaling that they are toxic or dangerous. This coloration serves as a defense mechanism to deter potential threats and predators from attacking them.
geese are not poisonous or otherwise dangerous, so their coloration is not warning away other animals. They do have predators though, so their coloration is for camouflage.
The benefit of the animal's coloration is that there are less chances of being eaten. What I mean is that it is less obvious to the animal's predators and therefore can survive and fool its predators. Coloration is a very important adaptation for some animals because it greatly helps them survive in the envvironment.
predators can easily spot them.
