my buddy just got one for his 75 and its doing great and is getting along with 6line, tang, and a couple neon gobies. havent done any research on them though. very cool looking too
I've got one in my 75. They're beautiful fish. I'm not sure that a 20g would be large enough for it though, as they do get a bit larger than bi-colors. At the least it's likely to end up being more agressive in a 20g than it would be in a larger tank.
i've had 1 in a 45 gallon tank for about a year now,its doing great.i can even hand feed it! it does get a bit aggressive at feeding time though often attacking my phantom blenny.they've got loads of character and are beautiful fish.
