Not sure if these guys are cherry head cross with redfoot(technically not hybrids but blah blah.), or just straight cherry heads. They don't have that marbling on the plastron or carapace, nor do they have that distinct black, leaf-like marking on the plastron.
I'm learning still guys.
"Not hybrid but blah blah" looks to me but I am still learning too.
My Redfoot has bright yellow marks on her head. The other two look like you posted.....and they were claimed cherry heads..
