How to tell L333 from L066

Hi, I have both and always thought I knew which was which, but lately I have seen L066 marked as L333 and vice versa. Is there an easy way to tell them apart? What do you look for?

Janne is better on these than me, but FWIW, forget stripes and look at the length of the fish particularly the head. If L066 is a "normal" proportion then L333 looks stubbier.

Jools explained very well what to look for, this is obvious with adults but if the specimen is small around 6-8 cm TL they can be quite difficult to tell apart...if some one mixed 10 L66 with 10 L333 in this size it would take a day to sort them out and still not feel 100% sure

The profil of the L333 body is higher then L66, the head like Jools wrote is more rounded and stubbier on L333, L66 is more elongated in their body and L333 is more compact.

Thanx for the info, it makes sense and I think I have been getting it right, even if I was not sure how!

I bought 3 adults of each on a trip to the UK and on return I put them together to Q for a few weeks, I never expected to have a problem separating them later, but I did. I am almost 100% sure I got it right.

Do they know the difference well enough not to crossbreed?

Just in case I got it wrong

They can crossbreed for sure, many similar species of Hypancistrus can and will crossbreed.

Ok, I better make sure I get the ID's correct so.

Alternatively that may be why I am having trouble IDing some of the ones I have seen locally lately, they may be crossbreeds.

Thanx again.

From all the images I have seen to date there also seems to be a difference in the tail on this fish. The L066's tail is more concave and the L333 seems to be straighter... or am I incorrect on that assumption?

You are correct when it comes to adults but with younger speciemen they are more similar and difficult to see the difference.
