Reviving a slightly old thread....
I have a 4line in QT and just learned that my LFS is getting a pink streaked in tomorrow. I'm trying to decide which would be a better choice for me. I have a 32 gal biocube. Tankmates are a Valentini puffer, flame hawk, yellow head goby and filefish. The puffer and flame hawk have gone after inverts but not other fish.
I need something to eat brown flatworms.
I couldn't have both in the same tank obviously, but if I purchase the pink streaked I could rehome the 4 line.
