If you’re new to Breeding Bristlenose Catfish / Plecos (and even if you’re not) then you’re probably aware that they are relatively easy to breed. Well, that’s the perception anyway . . . . . and in many cases it is true.

Having said that though, just like most things there is always more to the story, so if you’re thinking of Breeding your Bristlenose then it will pay to do some research before hand just so the whole exercise doesn’t just turn into one big fat waste of time.

So the first thing you will need to consider is whether to select a breeding pair or trio. A trio of one male Bristlenose and two females will increase your chances of a successful spawn. Whereas if you go for a pair you will then be assured of knowing exactly which female is the mother which might be important if you are breeding for specific bloodlines.

Next up you will need to buy a your breeders and there is one very important consideration here. Try and select breeders from separate bloodlines. It is very common amongst the Bristlenose Breeding community to breed siblings from the same spawn as it can be done successfully to achieve strong healthy fry.

Having said that though, if you do decided to buy some juvenile breeders from the same spawn then who’s to know how many generations back they have been interbred. At some stage in the lineage interbreeding will become a problem and the result will be weak fry that will be susceptible to illness and the end result might just be a very high mortality rate for your fry.

So if you want to save yourself a whole lot of wasted time breeding Bristlenose that may produce inferior fry then take some time to firstly find a reputable breeder. Make sure he can vouch for the lineage of his stock and secondly if he can’t, buy from separate sources to ensure diverse bloodlines. This way you should be assured that your fry will be strong and healthy and able to survive to adulthood.

Next up you will need to decide if you’d like to set up a specific tank just for breeding Bristlenose or if you’d like to place your Bristlenose in community tank with other fish species. Bristlenose will breed in a community tank and quite often this is the first introduction a fish keeper gets to breeding Bristlenose Catfish / Plecos. If you are serious though this is probably not the preferred method as there are some potential problems with this set up.

Breeding Bristlenose in their very own specific breeding tank will always reap the best results and this can be done with a minimum of fuss and effort. Firstly you will need a glass tank. Minimum size 2 ft or about 50 litres. You then need a breeding cave, some gravel, a heater, filtration and of course some wood for them to chew on. These are the basics you will need to get you going and you should be able to source them with a relatively minimal outlay by yourself.

Next you will need to decide whether you’d like to raise the fry to salable size in the breeding tank or a separate Grow Out Tank. If you decide to remove the fry then you will find that there will be a fair chance that you Bristlenose will breed again. So have a think about how well equipped you are to handle another spawn of up to 100 Bristlenose again, nearly straight after the last spawn.

If you find that breeding large quantities of Bristlenose back to back might tax you and your resources then just leave the fry in the breeding tank and this should be enough to stop your breeders from breeding again.

So there you have it. This is what you will need to know to get you started breeding Bristlenose. Obviously there is a lot more to it than that and I could add a lot more than this but honestly if I did I’d be doing you a disservice. By far the best way to learn about breeding Bristlenose is from an expert. It will save you time and it will save you money. I know, it did for me.

I’d like you to benefit from how I went about learning because believe me this is by far, 100%, the best way to go about finding out all you’ll need to know to successfully breed Bristlenose.

When I first got interested I searched the internet for information and came across an eBook written by a guy called Douglas Green who’d been breeding Bristlenose for over 10 years, so I bought it and read it and found it extremely helpful.

The eBook covers how to care for Bristlenose, plus you’ll find all the information you’ll need to know to breed them successfully. It includes information about how to breed Bristlenose in a community tank, which other species of fish can cause problems, how to set up a breeding tank, conditioning your breeders, triggering a spawn, setting up a grow out tank and how to go about selling your fry so your hobby ends up in the black and doesn’t cost you money.

So yes, if you get good at breeding Bristlenose Catfish, then there’s every chance you’ll cover your costs and still have money left over to spare. You see, Bristlenose are in demand because they are such good algae eaters and they can be kept happily with so many other fish.

That’s not bad, as there aren’t many hobbies you can take up that will actually make you money. As I’m sure you’re aware, most hobbies usually turn into a black hole when it comes to expenses.

    I have a female and a male bristlenose. They spawned and i counted 14 fry. The fry got smaller by the day. Now i have no fry. Could the mum or dad of eaten them? as I have no other fish in my tank. Just the mum and dad.

  • Hey Sandy, There are lots of reasons that the fry can die off. Unfortuantly, without knowing too much more there is little more than guess that i can do. However, the major causes of death of fry is if the water paramters are too far out of their range. Parents can deal with a huge range of conditions, however, the fry can’t and will sometimes die off. So, that would be where i would start. Another reason which is a bit more complicated and has to do with the fact that bristlenose are very inbred and as a result sometimes you end up with incompatable parents. The other thing to check is that they are getting the right food. Fresh cucumber is good for the fry as its very easy on their new digestive system, high protein food can cause complications.

    Either way, I very much doubt it was the parents who killed the fry but as mentioned above the they may have eaten the bodies. The other thing to check is the filter, sometimes they get sucked up into them and never get seen again. Either way i would recommend doing a large waterchange and maybe doesing the tank with some light antibacterial meds like Melafix just to be on the safe side.

    We have a pair of bitsltenosed plecos that have been breeding for some time successfully. However our last batch of eggs mysteriously dissappeared from our breeding cave. We have a few guppies in the tank and there was a lot of ramshorn snails. The only one that we saw in the cave with the eggs was the male pleco. Have male plecos been known to eat the eggs?

  • It has been known to happen from time to time. The big issue is why whould he have done it. There needs to be a big issue for a male bristlenose to eat his eggs. Normally if he gets stressed he will kick the eggs out of the cave, not eat them so the first thing i would suggest is check the tank for the eggs, the can often end up under logs and rocks etc.

    If he did in fact eat them then this usually indicates there has been a big stress event or the eggs were not viable. Stress events can include temp changes, changes in water parameters, distubance to the cave or health issues with the male. If the eggs were not viable then they may have been infected with fungus and in this case the male might eat them.

    Either way, he should be ready to breed again soon.
