Question about dwarves

What are different kinda of dwarf pikes? I'm interested in keeping a pair or two. I have spare tanks available. I have no idea how to care for them but I do keep ca/sa cichlids so I feel like I'm on the right track.

Tank mates? Temperament? Water params? Pictures would be appreciated or if there is a thread about this already a link would be helpful.


Thanks
