Abstract. This chapter reveals that there are significant complexities in the Trinidadian guppy system that make the investigation of the evolutionary ecology of the guppy both more challenging than it initially appears. The particular configuration of the river systems in Trinidad and distribution of fish species, including guppies, amongst
Gravid Spot. The gravid spot is a black area underneath your Guppy’s body, near the tail, which is a definite indication that your Guppy is female. A gravid spot does not exist in males. If it’s a female Guppy fry, look for a black region near the belly and anal fin, and you’ll be able to locate the gravid spot.
14. Amano Shrimp. Amano Shrimp. Larger in size than Cherry Shrimp, the Amano Shrimp are peaceful bottom dwellers that can be housed in a community freshwater tank provided they are kept along compatible fish like bettas, bristlenose fish and even guppies, and other peaceful, small-sized fish.
To produce high-quality guppy fry, you need high-quality guppy fish. As the number of guppies in your tank grows, separate close family members to stop inbreeding. Breeding similar species of guppies is a good idea. Doing so prevents interbreeding with other species. For instance, you can keep only fancy guppies and raise those.
