Small tomato plant has tomatoes!

One of my tomato plants has now got tomatoes. But the plant is really small and compact. 'Someone' tidied up all my tomato plants when they were seedlings and I don't know what the varieties are now :dh:.
what should I be doing now they have fruit?

 

Is it a bush type (i.e. a low growing one that doesn't need pinching out or staking)? Looks like it.

If so, just water and feed with tomato feed regularly, and enjoy your toms!
