Can Endler's Livebearer Live With Harlequin Rasbora?
Yes, Endler's Livebearers and Harlequin Rasboras coexist in 10 gallons or larger, and both species stay small and peaceful in community setups.
Why
- Endler's Livebearers grow to 1.5 inches. Harlequin Rasboras reach 2 inches. Neither species is large enough to eat the other.
- Temperature overlap 72-82°F covers both without compromise.
- pH 6.8-7.5 suits both. Both tolerate slightly alkaline water.
- Endler's occupy the upper levels. Harlequins school in the mid-level. Different swim zones reduce interaction.
What could go wrong
Endler's Livebearers reproduce frequently. Without a dense plant cover, fry disappear within days.
