Can Cherry Barb Live With Platy?
Yes, cherry barbs and platies share a 15-gallon tank well, with both species being peaceful community fish that tolerate overlapping water parameters.
Why
- Cherry barbs reach about 2 inches and cherry barb males display a vivid red color, while platies grow to 2.5 inches in a range of color varieties.
- Cherry barbs are peaceful schooling fish that stay in the middle and lower water levels, and platies are active mid-level swimmers that do not nip fins.
- Both species prefer slightly alkaline water with pH above 7.0, and the narrow overlap of 7.0-7.5 suits both comfortably.
- Temperature overlap of 73-80 degrees Fahrenheit covers the ideal ranges for both species.
- Cherry barbs need at least 6 in a group and platies are livebearers that can be kept as a pair or small group, making stocking flexible.
What could go wrong
If you keep male and female platies together, the livebearers will breed prolifically and fry numbers can overwhelm the tank quickly, even with the cherry barbs present.
