pretty much, size, body structure, and fry. southern Erectus are the only that hitch at birth. Northern erectus dont. Other wise they all require the same size tank, and temp.
there body is slightly different. but really, telling seahorse species apart, besides some, can be kinda hard. the erectus is what i originally was gonna get, there supposed to be the easiest to care for and to find. supposedly that is.
yep, ther ebody shapes are diff a bit. the kuda and kellogi you can see the kuda has more points on it's body and the erectus has lots of points and stuff.
