There's plenty of info on breeding these contained in the site if you put a little effort into searching it out. The things that seems key are that the fish must be of sufficient size/age and that they breed seasonally, so depending where you are in the world, they'll only breed between certain months and not in the other part of the year.
How big/old are yours?

The shanesworld article, http://www.planetcatfish.com/shanesworl ... cle_id=241 is likely going to be your best bet. I had a pair spawn within days of receiving my group. I'll add it was unsuccessful, but they don't seem like they're going to give much problem. They start a rainy season Wednesday, and at least one of the females appears to be anxiously awaiting.
Impossible only means that somebody hasn't done it correctly yet.
I've had breeding age adult Hypancistrus that took an entire year after purchasing before spawning for the first time. You can do everything right and still not get fish to spawn, but as long as you reasonably care for them like directed in the Shane's World article, it's just a matter of time.

I have them in a planted tank the male is a few years old. I got him when he was only about 2.5 inches he is know about 3 to 3.5 inches . The girls are about the same size . They came in as adults in october. I don't keep a heater in the tank. the temps are around the mid 70's in the winter and go up to 92 in the summer. I feed the raw round stake or boiled chicken liver every once and awhile. They are in a 30 gal long.
I would have thought there would be better food to condition them too than beef and poultry protein sources. A good quality pellet/flake food perhaps would get the females prime for breeding. Also offer a variety of possible spawning sites.
Motorcycles are not an expensive hobby, try keeping L-cats in Australia
1-do waterchange & clean 2-add controlled heat at the right temperature (in the link above or do search) 3- possibly up your flow rate 4-leave out the special treats...throw them on the barby for yourself...treats for these would be black worms, bloodworms,etc. 5-have patience 6-keep doing the regular water changes
I do water changes every few days from 50 to 75%. I just rearranged some of the plants yesterday so the water quality is not its best. I'm going to do another water change in a few days . I have to give the plants roots a little growing time before I do another water change
I was thinking of adding the ceramic pleco caves behind the stump. There are hides in the wood stump. The trunk to the right is hollow for about 8 inches. Thats where the male lives and undreneath has different deep nooks that is where one of the females stays. The other femal has a hid on the other side of the tank. It is shaped like a pleco cave. I hope you all don't think I'm playing around. I trying to find what I'm not doing. I been keeping fish since I was 5 and I'll be 49 in the end of june. I Breed, buy & sell fish and reptiles. I'm thiking if I add another trio to the tank may 2 males and 4 femals might stir the pot a little.
Have you already read the articles in Shane's world on breeding? The ones directly linked from their species page even? Steady temps, clean water, foods suited to their specific diet, caves of the appropriate shape, all should be provided for spawning attempts. Are the females conditioned and full of eggs looking? There is a TON of information on the site about these fish and others that breed very similarly. 1630 results, actually, all to be found Here.
yes. I have read it a few years ago when I first tried to breed them.I also read it twice this week I'm noticing one of my females coming out in the day for some reason. Here is a video of her. Thank yoiu for the info.
