how big is it?

 

[piranha_guy_dan]

4 inches

You can not identify a rhom without it's collection point. Even a guess based on physical characteristics is just that a guess and doesn't hold much water. People will try and make guesses like "it's a xingu" or "it's a diamond rhom" but it's still just a guess and isn't any more likely to be true than if you just guessed for yourself.

So it's just a rhom

 

[rbp 4 135]

ok that explains why the eye is not beginning to turn red, although at 4 inches he should show spots, either it is not a rohm altough, it certianly appears to be or it might, and i mean migh be a yellow rohm. it is hard if not impossible to tell what varient a rohm is without sufficent knowledge of a collection point

um...it might not be a rhom at all....it looks 1 hell of a lot like my ~6" brandtii ....the test to see if it is a brandtii si to take and draw a straight line from the back of the anal fin upwards...and if it passes through the dorsal fin it is prolly a brandtii *only species to have that feature*

here's a pic of mine when it was around that size:

another:

atleast that's my 2 cents....i'm no frank try posting in teh id forum

 

[piranha_guy_dan]

how about as it gets bigger is there a way to tell later on down the road?

 

[TheGreatHoe]

um you won't know exactly but u might have a lil better of an idea.... juvi serra's are hard to tell apart

 

[rbp 4 135]

well if it turns black then it is a rohm, or gets bigger than about 9 inches, or grows ridicously slow, then we know that it is a rohm.

 

[piranha_guy_dan]

i know by then how to tell if its a rhom or not.. with the red eyes and getting dark grey/black but i mean the TYPE of rhom can i tell that later on once he/she puts on some size?

 

[TheGreatHoe]

prolly not...you jsut need to know wut river he came from...if it came from teh rio sanfrancisco or wutever it is in brazil i'd bet 1 hell of a lotta money it's a brandtii

 

[elTwitcho]

No, unfortunately you can not.

 

[FootClanSkates]

looks very much like my brandtii as well. Not the best pics, but go here:

Edit: the small one in those pics is the brandtii, large is the rhom.

 

[dutchfrompredator]

i don't know what it is but it's pretty cool imo

 

[WorldBelow07]

yeah i dont know either. still badass fish

 

[traumatic]

Not a Rhom at all.....

I agree w/ the brandtii I.D. 100%

brandti are fairly easy to I.D.

1st, the anal fin begins halfway back from where the dorsal fin begins.
2nd, there is no black edge on the caudal fin in which a rhom does have. And in the brandti case that edge may or may not show up till the fish is larger.

 

[PARANHAZ69]

he looks just like my old brandtii..........i think its a brandtii :nod:

 

[BIGBLOCC 455]

brantii

a beautiful 1 at that.

 

[TheGreatHoe]

yea...my guess on brandtii was a good one...looks like i've learned something here afterall

 

[num1contenderNYC]

not to take your thread, but I have the same problem, I have 2 "Rhoms" from my local lfs and they don't know where they're from either. I have no idea what kind they are. Mine are like 3" each.
