The Blue Grass Guppies was first imported into Australia in 2017 and they were popular at the onset. They are different from the cobra guppies as the black dots that is evident on there caudal (tail) fin is finer and it looks like pepper.
The females looks very similar to the males and evident with the small pepper on it as well.
A stunning and still a rare species to have in Australia.
This is a very sensitive strain where they can get Columnaris very easily, we recommend that you use API Aquarium Salt and API Melafix
