I am going crazy which pleco is this (L66 or L333)

[Hellfish69]

Hello,

i need help by identifying this plecos here. I got them several years ago and i forget this stupid L number of these guys.
I was not at home for 2 or 3 days and in my tank the filter stop`s working => outcome 4 fishes dead .
Now i need some new prisoners for my group, but which one.
Maybe someone can help me.

greetings
Mike

Looking at the small caudal peduncle and well-forked tail in the second photo from top, I'd guess

L066

. But I hate ID'ing these Black & White lined Hypans. Ugh! I hope someone can confirm the ID.

Cheers, Eric
