I've ruled out all types of ponies except for the H. Reidi & H. Kuda. Any rule of thumb on how to tell the 2 apart without a photo ID? Just wondering what the species is that I bought my daughter over a year ago. Both were bought as "yellow sea horses" but changed to black within a week. Both have black spots. The male is 4.5 to 5" when tail is streached straight. (female is still a baby as the last female died 3 months into it & we didn't replace her untill 2 months ago) She is about 3-3.5" when tail is straight. Both do well in temps from the mid 70s to about 81 degrees F. with no ill effects. Any knowledge on how to tell Kuda from Reidi would be great. Thanks in advance!
