Can I House different species of M. Estherae like Red, OB, O and blue in the same aquarium? Is it okay to let them breed?????

If they're all from the same collection point (most often they're Minos Reef variety) then you can house them together and let them breed.

If they're from different collection points, you can still keep them together, but any fry produced should be considered hybrids.

If you're unsure (or the seller is unsure) of their origin, it's best to err on the side of caution.
