Mono or not Mono??

i got these 2 big guys as monos and i am not sure they are the same type.
the bigger guy looks alot differnt then the smaller one.
i have 3 Pbass and I know one is a temensis what are the other 2?

Thanks for the ID.
hidden behind the egg crate in the pics is my latest pickup.
A 3" kelbri will try for a pic of him tonight.
does not look like much at this point same as all little pbass do.
I love the way the 2 monos and my temensis beg for food when ever i enter the room.
they remind me of a dog a dinner time...lol
