Metynnis argenteus vs. Metynnis hypsauchen
I am still a little unsure the difference between these two species. I have researched lots of sites and I am still finding conflicting information. I did read the information on this site as well but I would like to know more.
Does Metynnis argenteus have the red anal fin ?
How do you distinguish the difference when they are young? or is the color present throughout its life?
I seem to prefer the fish with the splash of red but considering how frequently these guys are labeled incorrectly I want to be 100% sure of what I am getting.
I have a 55 gallon set up and I know these are what I want. I find them so adorable and beautiful, the prefect combo. I am planning on getting 5. My tank is about 3 years old and I have really been pondering where I want to go with it. I have a school of 6 Panda Corydoras keeping the up the place :) The big delay is probably due to the fact that I have always had a soft spot for pacu, but they are not really appropriate for me since they will get so large and need a multi hundred gallon tank. These silver dollars, being relatives of pacu, seem like a perfect choice for me and I am very anxious for more feed back on distinguishing the difference between these two species.
Thank you very much,
