any cactus people...

i think the one in the foreground might be a mamalaria, but only a vague memory.

I think the one right side at the back is Pilosocereus leucocephalus, the left one looks like an oputina of some kind...(bunny ears)....cant remember the others....

thanks, i'll have a look at those suggestions on google images.

The one in the front coukld be a Mammillaria or Rebutia

Thanks, looks like they are Pilosocereus leucocephalus, Opuntia and Rebutia.
