How many different types of silver dollars are there? I have three, one looks typical all silver with a red anal fin. The other two have red and or black on dorsal and tail as well. They also have red below the mouth. Two different ones or just color differences?
 
Anyone :feedback:
 
Regular sd then, the evil looking ones

Never seen that 2nd kind before. There are a bunch of different kinds though, I've seen pics of some that had a gold tint to them, I think they were genus Mylossoma rather than Metynnis, and they didn't get as big as the common Metynnis.
 
Guess what... their the same species AND.....

The top ones female, bottom ones male........ and he's horny!!! :ROFL:

Look at the anal fin.... the female's is straight and the male has a "bump" in it...

The red cheeks,black dorsal fin and black tail mean he wants to get it on.
they may also get 2 dark blotches on their sides just behind the gills.

How big are they? He may start chasing her around and if their sexually mature he'll swim beside her and wrap his anal fin over hers as she releases 5 or so eggs at a time.... they'll do this for hours.


Mine spawned 3 days ago.... i now have little wrigglers in a tumbler :D

I'm only playin mate.

Mine do it on the odd occasion, they seem to get confused lol

If you have a second tank, i'd take one male out and see if the other one starts chasing the females instead :D
