Thanks so much for the replies !

I really think they are beautiful fish, but if they really do like alittle aquarium salt, then I guess I cant keep them with my tetras. hmmm... will have to think about that some more.

Zerotona, your Ginger is gorgeous and yes, I can see the aquablue in his fins. Perfect name for him with the ginger colored specks. The sailfin that I saw at the store was a black/white spotted one and was very interested in a female there and was showing off his fins.
IF I had to use the salt, is there any other fish that can tolorate that as well?
thanks again, ~ kate
