I am bringing some for BAP tomorrow. Since they are not a well known species. The are in the group of guppy-like species. They care is similar to Endlers. The females are more silver in color tan tan. The males take longer to color up than Endlers and have a lar square dorsal fins. With colder temperatures more males are born. The with warm temperatures the opposite is true. I bought the4m from Rick Borstein from the Chicago Livebearers association table at the swap.They are eat to care for.
