Is it is a rasbora or a tetra? I've seen it classified as both.

 

[jpepe1]

It's commonly referred to as a tetra but these are only common names that mean very little. If you want to see what fish are closely related go by it's scientific name,Hemmigramus rhodostomus,and look for other fish of the Hemmigrammus genus

 

[jimscott]

Way back when, I saw them listed as both. That prompted me to Google it. The first 2 entries were Tetra & Rasbora. If I remember correctly. Hemigramus is the genus name for tetras. What makes a rasbora a rasbora?

 

[jpepe1]

Hemmigrammus is only one genus of fish that is commonly referred to as a tetra. Neons are in a different genus for example but are still called tetras.Black tetras are in a third genus and it goes on and on. There really aren't any rules for common names which can often lead to confusion.

 

[Crazyfish]

Classifications are made by certain characteristics which sometimes fall on the borderline of 2 or more species.... it doesnt necessarily reflect behavior of the fish... in other words, not all tetras are alike even though they share common characteristics.

Fin structure is one of the primary means of identifying the family to which a fish belongs.

For example, tetras have an adipose fin between the dorsal and caudal fins, while cypranids do not. So whether it is a tetra or a rasbora is determined by the adipose fin, or lack thereof.

It's a tetra.

 

[jpepe1]

Rasboras aren't cypranids ,they are characins.

 

[jaysee]

Rasboras aren't cypranids ,they are characins.

That is incorrect.

 

[jpepe1]

I'm only wrong about five times a day so I'm going to double check

 

[jpepe1]

Just double checked .They are characins

How about a link?

Minnows are cypranids

Don't know how to post a link,I'm pitiful with computers but if you google Hemmigramus you will see were weald aquatics describing the rummynose

How many more sources do I need to provide?

 

[jpepe1]

I see where your source agrees with you.Did you see where my source agrees with me? Odd

Yes because you are looking up a genus of tetra, not a rasbora.

Rasboras are cypranids. There is no debate.

Fish of the genus Hemigrammus have adipose dorsal fins, which as I said is a distinguishing factor of tetra species.

 

[jpepe1]

ok Iv see the issue and it's my fault .You are stating rasboras are cyprinids and you are correct.I was trying to say rummynose are characins and I mispoke (mistyped).My mistake

 

[jaysee]

I agree that rummy nose are tetras - said it in my first post

 

[jpepe1]

Is this how wars start?
