Good Vibrations.....?

[kat and james]

hi
our we have three silver dollars in a 50 gallon tank, one is about 2 inchs across and is very round, while the other two are slightly more elongated, and are about 2.5 inchs across.

the two larger ones spend all thier time together, leaving the third one to it's own devices most of the time. however recently these two larger ones have been seen swimming side by side really close, with their tail fins touching, they then start to vibrate really quickly against each other.

is this some kind of mating ritual or are they just playing?

thanks
kat

Don't hold me to it as I don't and have never kept Silver dollars. But it sounds like spawning activity to me. Assuming they're not actually trying the body smack which tends to be a sign of hierarchy sorting in some fish.

According to CFC's profile on Silver Dollars, breeding is rare but it sounds as if that is what they are doing.

that is what we thought, what i have read about breeding seems to be that they can breed in captivity, but only when there is a large group!

funnily enough we also thought that these two were of the same sex.....
