Identify my new pleco collection

[Yourivsnl]

Hello,

I bought a week ago an aquarium with a big collection of pleco. The old owner could'nt tell me the exact names and L-numbers.
I tried to identify them but the differences are small, especially without any knowledge about them.


I guess this is a L144.


L181?


L103?


Unknown


There are more than 5 of these small ones, maybe a mix of the L144 and the picture above this one?



These two look like L400 or L401.

Hopefully someone can makes things more clear, thanks in advance.

Hello Yourivsnl,

Welcome to Planetcatfish!

I'll do my best to help with IDs.

I guess this is a L144.

Ancistrus sp(4)

L181?

Hypancistrus. Possibly

Hypancistrus sp(l004)

L103?

Hypancistrus, possibly

Hypancistrus sp(l340)

Unknown

Long-fin common bristlenose,

Ancistrus cf_cirrhosus

There are more than 5 of these small ones, maybe a mix of the L144 and the picture above this one?

Short-fin common bristlenose,

Ancistrus cf_cirrhosus

Yes, these could be hybrid fry from the brown long-fin fish (female, assuming she's large enough to breed) and the albino dark-eyed fish (male).

These two look like L400 or L401.

If you don't know the source of these fish, or whether they're wild caught or captive bred (and possibly hybrids of two similar species), ID'ing them can be a horrible task. But your guesses are plausible. The fish don't look very big, and in my experience the appearance changes a lot as they age, so I'm not certain.

Cheers,

Hi,

I agree with Eric concerning the Ancistrus. The first Hypancistrus (assumed L 181) is Hypancistrus margaritatus (L 404). The second one (assumed L 103) is a Hypancistrus from the Xingu River, possibly L 333. The two last ones reminded me of the first presentation of L 399 and L 400, which were shown in an almost identical way in the magazine, but obviously thats of no matter here. I guess both are L 400, definitely not L 401.
