My multies are still very skittish and I was thinking about getting some dithers for them. Right now I have 4 adults in a 15g with about 10-20+ fry of various sizes. I was thinking about getting some gertrudae rainbowfish as dithers. Would that be a decent option for the multies? I figure size wise it works. Or any other options are welcome too. I have some endlers growing out I could use as well.
