Aequidens rivulatus

  • We are currently upgrading MFK. thanks! -neo
well about the silver and sibler saum u tell the difference the they both have sivler edges and so does the Aequidens rivulatus but the silber has the coloring on the scales and the rest have it around the scales then to break down the Aequidens rivulatus from the gold and silver saum. the aequidens rivulatus has different colors around the scales. so i am going to sum it up like this i will wait until they get alot bigger to decide but for sure they are not the gold or silver saum

If Rapps says he sold you rivulatus then I am sure that is what you got. I would have gotten some if I didn't already have two gold saums (I mean green terrors lol) that I love. :ROFL:

i will be happy whether i have what is described as the sibler saum or Aequidens rivulatus

Of all of the fish I have owned I just love my saums. I have no doubt you are absolutely correct with what you just said. Just watch out as they can really be the terrors purported. My Precious has (with a little help from my convict Julio I suspect) ripped in half a small pleco and killed two crawfish.

Once I put in 6 silver dollars though my tank has become simply awesome and everyone gets along perfectly. In fact, sometimes my Precious seems to almost treat the SDs like they are groupies or worshippers or something.

Kinda hard to use scientific nomenclature when these fish have not been described by the ICZN.

That is kinda my point. Is the question "What is the true A. rivulatus?" or "what is the true green terror?". The difference is that there are ways to prove the first one, but you cannot prove the second one. When a species is described and given a Latin name then its all official, like your real name on your birth certificate. A common name is more like a nick name that you get at school, while it may be what a lot of people know you as, there is nothing to prove it and it certainly can't be used in any official sense like on a drivers license or in court.

Somewhere there will be a description for the fish classified as Aequidens rivulatus, and it will be linked to a type locality from where the fish that was described comes from. There will be other populations of similar fish that may be the same species, or a subspecies, or just closely related species in the same genus. The classification will change depending on the opinion of the person doing the research, splitters and lumpers etc. Some may remain unclassified, and there will always be confusion and conflicting opinions surrounding them, and untill they are acrually described and classified then it is all speculation. And as for fish in the hobby, unless they are wild caught from a known locality, its pretty pointless argueing over the finer points of their classification unless you are 100% sure of their origins, which, lets face it, the vast majority of people keeping "green terrors" arent.

Yeah I seen a vendor selling gold saums as "wild caught", is he lying?

No, well not unless they were captive bred.

What I'm getting at is that a bunch of hobbyists who have never written a description of a species (apologies to anyone here who actually has) and probably aren't even sure of what constitutes a valid species arguing about the 'trueness' of a group of fish that even the experts are yet to make sense of and classify is a bit pointless. [no offence to anyone]
 
being wild has nothing to do with why is called silver saum or gold saum or true green terror or sibler saum or Aequidens rivulatus
