Moving my four older guahiborum from a measly 10 gal to a 40 gal (dimensionally only 37 gal) where they will join two younger specimens. Maybe now something will happen.

When I pulled them from the tank I was surprised at how big they had gotten - the big male is now 85mm SL. The largest wild specimens reach 125mm, I can't imagine what they look like at that size. YIKES! :-SS :YMAPPLAUSE: :YMDAYDREAM:

Notice you can still ID the female from the bent pectoral spine. When I first bought her, she arrived with a broken and bleeding left pectoral spine, and a deformed right spine. In these photos, you can still see the bent right pectoral spine.

Cheers, Eric

Two other unsexed specimens. I believe they both might be subordinate males, or the top (70mm SL) is female and the bottom (75mm SL) is male. The possible sexing difference is suggested by the relative lengths of the pelvic fins (on my sexed fish, the male has larger pelvic fins).

Thanks @ridout for noticing the difference. :-)

Here's the tank they went into - a 40 gal standard tank (really 37 gal) with HMF on the right side. One fish is visible in the cave at the bottom left side of tank.

Very nice setup and fish Eric! I actually got some of the L106's too about the same time you got yours. I need to move mine as well.... they are in a 20 long and they are getting to the point that a little more space is needed.

Thanks, Chuck.

I'm curious how fast yours are growing. How big are yours now? What are you feeding yours? I haven't had mine on any special diet. In fact, I'm not really sure what they like! :)) Honestly, I think their main food is wood. They eat other foods, but nothing voraciously and I often have to remove uneaten food (shrimp, clams, sweet potato).

I hope yours breed for you too...

...

... I just hope mine breed first. =)) :)) :- :YMHUG: ^:)^

{To be honest, I'll be shocked if mine ever breed. They seem to like sitting on their fins, watching my hair turn more gray! :))}

Cheers, Eric

I would guess you got another Pair there. Dichromatismus seems to be a thing with many plecos, especially when you remove them from their comfort zone, males tend to lose a lot of colouration while females stay calmer (they are not obsessed about losing their silly caves xD). Top specimen seems to be rounder as well.

If the new tank is all settled in and running well, I would go for very soft water, like doing some WC with pure RO water. Then do nothing for at least one month. No Waterchanges. Nitrate will raise and PH will drop. Only visit them once a day for feeding, leave them alone as far as possible. Hands out of the tank! :D

If you got no spawns after 4-6 weeks, do a big Waterchange with slightly colder, hard tap water. Chances are high you might see spawns before or after the waterchange.

I had spawns on L183, L260 and L168/52 during the "no waterchange"-phases and spawns on L134 after the waterchange.

I guess it will be a race to see who gets them to breed first them! lol I did have a trapping for a couple days..... nothing come of it. I haven't been feeding anything special really.... just my normal mix of pellet and stick foods with the occasional treat of blood worms or whatnot. They always seem to eat everything I put in there. Mine aren't to picky when it come to feeding time. I will have to get back to you on their size. I know they have grown but I have no idea how much.

Chuck

I have a feeling that they are like L147's and L377's when it come to breeding.... and just takes time for them to mature and the right conditions. But we will see.....

Thanks for the ideas Johannes. Yes the upper fish is a little wider and has the shorter pelvic fins than the lower fish, so I might have two pairs. Plus I have two small fish in the tank too, much too small to breed, but they will grow. As for dichromatic color, you may be right for this pair, but the larger male and female are exactly the same color (you can see in their dorsal photos), so I'm not sure how consistent or reliable that difference will be.

As for the water manipulations, this tank is at my work, so it's not going to get a lot of attention or manipulation on a daily basis; perhaps it will get a little more neglect than my other tanks. While I won't intentionally give it a dry season/wet season cycle, that may end up happening if work is crazy busy. :)).

Thanks for the extra info Chuck. And I agree, the fish probably just need to mature to a size where they feel ready. Best of luck to you. Between you, me, and everyone else keeping these, I know someone will spawn them. I suspect someone, somewhere has already spawned them. And I know for a fact that someone in Europe has spawned the related fish, . I saw photos on Facebook.

I measured one of them today.... she was just over 5" TL so about 10.5cm SL. It will be interesting to see how yours do compared to mine..... I looked up exactly when I got mine and it was August of 2015. Can't remember how big they where when I first got them.... but they are about the same size now at least.

Thanks again Chuck.

I got my first fish Dec 2015. At the time, the largest was 60mm SL and the smallest two about 50mm SL (the other three were 55mm SL). I had two die from that group of six, but I don't know if either of the dead fish was my largest or smallest (I wish I could know). From my photos yesterday, my large male is now approximately 110mm TL = 4.3" TL... Much smaller than yours, which must be whoppers! :YMAPPLAUSE:

Please keep me informed of your progress, as I will you via this thread.

Cheers, Eric

@Racoll, this next post reminds me of you. :-) My exercise and efforts are fraught with error, but since the results were as predicted, I'm encouraged to know if the same data could be obtained with more careful photos/measurements from a greater number of fish.

Hi All, As mentioned above, it was brought to my attention that the male H. guahiborum might have larger (relatively speaking) pelvic fins than do females of the same species.

I have four fish to examine from the above photos - 1 male, 1 female, and 2 uncertain, but quite likely (based on body shape hints) another male and female (but maybe two subordinate males). So I took the time to use the dorsal view images of all four fish to measure the pixel sizes of the visible portions of the pectoral and pelvic fins of each specimen, then convert these to millimeters and express the results as a ratio of Pectoral spine length / Pelvic spine length. The idea of this ratio is that if the pelvic fins are bigger on males than on females, we would expect the ratio to be smaller in males (because the larger pelvic fins are in the denominator of the ratio above). Below are the results, including the text from a post on the same matter I created on Facebook. When you examine the numbers, the sexed male and the "unsexed but likely" male fish both have smaller ratios than either the sexed female or the "unsexed but likely female," and for both gender pairs (male or female) the two specimens that "might" be the same sex have about the same ratio
bekateen wrote:We should never try to do statistical comparisons on an "N of 1" but in this case I thought I'd play with the idea that the pelvic fin lengths differ between genders. The yellow column shows the ratio of pectoral spine length to pelvic spine length (each measured as a straight line) for all four fish. The first fish is the definite male. The second fish is the definite female (unfortunately only one pelvic fin is visible). The third fish is unsexed (top fish in the photo), possibly a female. The fourth fish is also unsexed (bottom fish in the photo), possibly male. IF the sexes of the two unsexed fish are correct, then yes, these two males have longer (visible) pelvic fins than do females. Both "males" have an average pectoral fin length to pelvic fin length ratio less than 1.5, and both "females" have an average value >1.5. Don't make too much of this, and please don't call me out on my interpretation. (1) I've already stated we shouldn't trust an "N of 1" (i.e., the number of definite males and definite females), (2) I'm not publishing this, and (3) maybe the difference is just an artifact: perhaps the pelvic fins "look" shorter on females because a portion of the fins is hidden by the increased girth of the females. Of course, if either of the unsexed fish are mis-ID'd for gender, then this all washes out and we see no differences whatsoever. LOL Cheers, Eric

Pretty interesting work there. TBH with pure eyesight I can hardly see a difference in Pelvics :D

Too bad there is no picture of the second female from a more straight downward shot.
I guess no differences were to be seen on the vents neither?

Previous photos of the vents were rather inconclusive, but I thought there might be some differences. I have pics of the vents of just the biggest male and female, but I couldn't see anything convincing me. I'll post them later.

This is true in many plecs..... not all mind you but it is a good guide at least. This works well in sexing Hypancistrus, Peckoltia, and a few more that I have noticed anyways. I tell people that are new to sexing them to look for this as I think it is easier way for them than trying to sex them by body shape, head shape, ect.

Thanks Chuck. Indeed yes; I just wasn't expecting it in these fish. And it is pretty subtle in my photos and it is in need of confirmation through better pics (ventral views so none of the fins are hidden along their lengths).

Hi All,

Here's an update on my . Still no signs of spawning, but at least the dominant male is growing well. In the last 16 months, He's grown to about 10.2cm SL, more than 1.5cm longer than my last measurement! There's also one female that is distinctly large, but not as large as the male and I didn't measure her to confirm SL. The other four are significantly smaller in size. I couldn't tell if it was real or my imagination, but the pelvic fins of the big male seemed disproportionately long.... and orange in color. :YMDAYDREAM: He also had really big pectoral and opercular odontodes.

I rearranged their tank today and added a large WC, about 75% distilled water and 25% tap water.

Hopefully something happens, but at least for now I'm really impressed with their growth and health.

Cheers, Eric

Mine have been acting like they want to breed..... and the biggest male is impressive. I haven't measured them, I should have just didn't think of it when I moved them the other day. I will try and get some measurements and pictures in a few days so we can compare our finding.

Helpfull topic Eric! I keep a male Hemiancistrus guahiborum for more than 6 years, and is kind of forggoten by me. I intend to pay more attention at this species and I' m planning to get a group of them. Are there any news from your tank? Any breeding attempts?

Greetings, Chris

Good morning, Chris,

No new news regarding breeding. I'm still trying to get them to breed, but no sign yet.

Most interesting, all but one have turned yellow, almost white, in their tank. This started several months ago. I wondered if it is a sign of stress and maybe it is, but I've had no deaths after all this time so if it is pathological, it is a slow or mild effect.

I first saw it in the same species at the local fish store where i bought mine. However, this group of fish is a newer arrival than mine, so they didn't arrive in the same importation.

I'll try to get pictures of my fish. They are quite spectacular, almost ghost like.

Now I'm wondering if it might be caused by a mineral deficiency, so next week I'm going to experiment by adding pond clay that is used to enhance color in koi.

Cheers, Eric

Hi Eric,
I also had seen the change of colour you describe at my L106, a couple of years ago. If i can remember correct, it was after a change of tanks, so i gave him time to acclimatize. The colours came back to usual after a few days.
I believe the fish of yours that got pale, are from ruinemans. In Greece is probably the importer with the best quality, although a bit pricey. So i believe and wish there are no problems with yours too. Looking forward your updates.
Greetings, Chris.

I haven't seen this in my L106's..... but I have seen it in other plecs. Do you have light colored substrate in the tank Eric? The only time I have seen this in my plecs is when have white or light colored sand/gravel..

Substrate is a typical light sand (It's conventional pool filter stand). So yes, in my tanks that might be a factor. But at the LFS where the fish also went pale, his tank had medium shade blue-painted gravel.

I believe it is a way to camouflage themselves to their surroundings..... I haven't seen any plec do this when they have dark substrate or no substrate (BB) at all. I don't have many tanks with dark substrate but I have noticed for example L76 are lighter in a tank with white sand than they are in a BB tank as well..... not the yellow/white color like I have seen in other plecs but very light compared to the others I have in the BB tank. I don't believe they are stressed as they come out when they know I am right there to eat or just to play....

Take care,
Chuck

Not the best pictures, but here are three of my own fish (not fish at LFS) today.
