My first thought was a pictus, they always resembled dalmations to me, lol. From what I have researched, their are 2 varieties. The Peruvian pictus have fewer large spots on the body with smaller spots on the head. The Colombian variety have more smaller spots on the body and tiny spots on the head. They are very active fish best in groups of at least 3 to really enjoy a more natural behavior of this species.
*edit* rofl, I just read the link posted above by Carolinyens.
