I have a 55 gallon tanganyika tank that has only four lamprologus multifasciatus in it currently. I am looking for interesting active colorful fish from Tanganyika to add to the tank. I was thinking a smaller variety of cyprichromis leptosoma, or a pair of Julidochromis transcripts, or Paracyprichromis nigrippinis. Or a combination of these. What do you all think and what would be ideal? Thanks!!!!
