Red Comet Crown Ram

[ALEXF]

I was in a lfs, an actually really good one that specializes in fish and i cam across what they called a red comet crown ram, they also had a ballon ram both looked similar in color to a bolivian ram now my question is i am sure its just a slightly different breed but will it grow to about the same size or is it possible for it to grow insanely different? i tried to google it but couldnt find anything. is there any ram experts here???

Thank You,

Alex
