I have kept banded pipes, bluestripes, dwarf pugnose pipes. The pugnose reproduced numerous times for me. Bluestripes were very nice as they were small and colorful. I mostly fed them enriched bbs, since I have so much of it for my dwarf seahorses. The pugnose also ate enriched bbs. The banded pipes didn't last very long, unfortunately.
Keep in mind, the pipes will be WC, even if they are eating frozen foods. There are no commercial breeders in the US or abroad that are selling in the US.
