thanks gecko
ive read all them before it still does'nt give me whats their max adult size,
are they aggressive towards others

**Gecko** · 26th Aug 2008, 17:06

Since they are relatively newly discovered, not much is written...but fair to say that they will not differ too much from the rest of the Hypancistrus spp...max size should be as per L66 or L400. Aggression level towards con sp. should be high since they are territorial and would need to fight for premium cave space for breeding. My 2 cents

**celticfish** · 26th Aug 2008, 17:22

I'm guessing they will be in the range of a L066 in size.
Probably under 5" TL or 4" SL.
The reason I say this is because the largest specimens seen in our LFS are about that range.
And they look like adults too.
Not quite near as massive as some L333's that came in this season.

I could be wrong though...

As we may not have seen the largest specimens yet.
Its just speculation on my part at this point base on what I've seen in LFS stocks.

It is impossible to typecast these fish, since there are at least three, and probably more, different species in the designation.

**windy1958** · 7th Sep 2008, 17:34

i think i have 2 different sps in the tank
2 of them look like hypancistrus gurupa, as for the other 2 got no idea

Well, god damn, you better watch out---given your very successful breeding track record, you don't want those guys hybridizing.

**eeeeemo** · 7th Sep 2008, 21:12

i have seen your album. you have one L400 and one lower xingu.

**genes** · 7th Sep 2008, 23:55

Hi windy

Would be great if you could post the pictures of your 2 species here.

**windy1958** · 8th Sep 2008, 06:09

just added 2 new pics to gallery

**genes** · 8th Sep 2008, 14:12

I'll post the pictures up here for easy referencing. So these are also known as L318?

Windy's Lower Xingu sp.

**eeeeemo** · 8th Sep 2008, 22:14

hmm eugene, these aren't her only pictures..
got the unknown hypan one.. the unknown hypan is a L400 and the 1st picture above is L318 and bottom is lower xingu.

**Cup** · 8th Sep 2008, 23:47

something along the lines of 99% of most L-318 are not in fact that animal. The original fish listed in DATZ is nowadays considered L-401 (or so a few believe), thus the true nature of the number remains to be elucidated.

eeeemo

im a HIM not a HER

**johannes** · 9th Sep 2008, 09:13

hey guys how about these?

i have plenty of these and all has belly markings, btw their body markings are varied as well, some with shorter and thicker lines...

labelled as L340 in every shop that sells them

i have 5-6 males at the size of 8-9 cm TL (6-7 cmSL) showing distinct odontodes and hairy pectorals.

some even look like windy's first picture

thanks..

Dudes,

How about we refer to My Aqualog "all L-numbers" for some answers? or maybe more questions haha. But unfortunately, lower xingu is not inside the book.
