Standard bn or ?

Ok, feeling like a dummy even asking this but until 2 weeks ago (before I discovered this forum) I had no idea as to how many BN morph/varieties there are. If you guys would be so kind to look at the fish in my profile pic and either tell me it is a common bn (it is a juvie 2+ inches long ) or an L182 ? Seems the more I google the more confused i get. I trust you guys know what I have . Btw, thanks you guys are the coolest.

I can only see the pic as an icon, but am interested to see some more pics

Don't know if you can see in the pics but the fish have a bit of a seam on the dorsal and caudal fins. Not bright white but somewhat of a grey. On the dorsal it is widest at the top and thinner towards the back and on the caudal it is thin at the center and wider at top and bottom

I believe they are common, here is a pic of some of mine to compare

Commons, the white seam on the dorsal and caudal fins dissappears as they mature (sadly). Usually the white on the edges of the dorsal fin are the last to go.

It appears mine are indeed commons.
I have 2 small males and I'm looking forward to watching them grow.

I was unaware that the seam disapears tho
I was looking at some lf's with beautiful full,
white seams that I believe were commons.
The breeder stated that he selectively bred them for the seam.
Is there a variety of commons that retain their seams ?

Thanks for all your help

Ancistrus Dolichopterus or the L183 is often called "Whiteseam" due to the fact it keeps the seams into adulthood.

Many types of BN have whiteseams when young but lose them as they develop.

I recently saw some large juvenile BN's marked up as Ancistrus sp. Guam and they had white seams on their tails but whether they keep them to adulthood I don't know.

I also saw some lf white seams on aquabid.
the seller noted he selectively bred them for attractive seams
I think they were listed as commons and looked like commons . But can't be sure

I thought about bidding on them but now I'm happy I bought Calicos instead

I wouldn't mind a few L183's in my collection. They are my next "want" Beautiful fish !!

they are beautiful

They will be longfin commons with a bit of white on the seam. the longfins seem to hold theirs for a bit longer but it will go over time.

The L183 and associated species do not have a longfin morph, as much as people have tried, they havent cracked it.
