Diamond Tetras: are they nippy?

[PineSong]

I would like to add 8 or so diamond tetras to my 29g male guppy tank.

Reading online it seems many sites say diamonds are peaceful and can be housed with guppies. Others say they may nip fins. Others suggest that higher numbers of diamond tetras will be more peaceful and they tend to be bothersome more when there are not enough of them.

If you've kept them, what was your experience?

Kept and bred them, in my experience they'll be fine be guppies.

Have fun!!

I have a group of 11 in my 75 gallon and they leave all the other fish alone. They do get rambunctious during feeding time and the males tend to be territorial towards their own in certain densely planted areas.  Also they seem to breed easily i have had found 3 fry without actually trying to breed them.

Same experience here, my diamonds were in a mixed tank with many different species including guppies, have never seen the tetras being nippy. Fast feeders, yes.

Diamonds might outshine the guppies in a sunlit tank :)
