View Full Version : Breeding Bristlenose

Hi guys,

This is the little story of how I was surprised by the arrival of several BN fry.

I was recently forced to move all of my fish from one aquarium to another in the space of a few hours. The reason for this is that quite simply the other aquarium cracked and all hell broke loose.

We prioritized the move, of course, and were able to save all but one Glowlight. I then moved all the gravel, plants and rocks.

Over the course of the next day I was fascinated by the behaviour of the male BN; he was excavating a cave under one of the rocks. I have never had a BN do this before. If the truth is to be told I was tempted to try and stop him in case the rock was unstable. However, nature has been getting it right long before I was involved so I left him to do his thing.

The female joined him and they remained under there for about a day. Then suddenly she just swam away and stayed on the other side of the tank. I never thought to check if she was thinner or not.

A few more days passed and then I subsequently left on an 8 day holiday. My parents looked after the tank whilst I was gone. So I was reasonably confident that the fish would be okay.

So... I came back from my holiday this week and lo and behold; there were several tiny BN swimming in the tank!

The above photos are the two parents and one of the fry. The fry are seemingly impossible to photograph.

So now that we have the background story there are several questions that I would like to ask...

1) How many eggs do they actually lay?

2) What is the usual number of fry that actually hatch? I only have 4 little ones :(

3) What factors play a role in the above number of hatch-lings?

4) How often will they spawn?

5) Are there any special foods that should be provided for them? I currently provide algae wafers, cucumber and baby marrow.

Any other suggestions and advice will be more than welcome.

Thanks!

Sadly not one of them is golden. They all took after their mommy.

Though, the light stripes on the fry are much brighter and more golden than the female. I'm not sure though if that is a result of them being young.

Should be interesting to see what they'll look like as adults! I've had a pair of albino bristlenose breed frequently....but due to vigorous gravel vacuuming I really don't know how many eggs they had at a time. I eventually started taking the young to my lfs and recently took the mated pair to the same lfs because the load on my tank was too much. I kept one young one only. I didn't feed any differently when the young were in the tank....they seem to eat pretty much anything...and of course love algae... They really are beautiful fish!!

Thank you :).

I am aiming to keep one of the young for myself and to give another to a friend. I am in desperate need of another algae eater in my second tank, so what better solution than to keep a free one :).

This is his tank. He likes the big rock on the left.

My pair are the same coloration you have - male albino and brown female. Their first spawn there were about 15-17 fry. The 2nd spawn about the same. Not one albino in the bunch! All look like mom, although they have white edging to the dorsal and tail fins that mom doesn't have. Not sure if she had it when younger.

Female BN typically lay 50-100 eggs, depending on their size and maturity. Omce they start they usually keep spawning for several more rounds before taking a break. When they're tiny fry they don't have spines like the adults, and are easily eaten by other fish. They also need fed a bit more often when small, no fat reserves and the adults likely have the tank cleaned thoroughly of grazing material already.

Okay, so I need to create some more hidey holes for the little guys! I took some advice from my favourite fish store to use some PVC piping that I can coat with gravel. I've made the pipe 20cm long so it will leave a little bit of space on either end for them. It is also wide enough to accommodate both parents with a bit of a tight fit.

I will also feed them a bit more regularly. However, the timing was almost perfect since the algae has grown quite a lot! (I discovered I was giving around 11 hours of triple T5 lighting. This has been cut down to 7 hours.)

1. This is a common? 30-40, sometimes more if they're several years old
2. Depends on how proficient the male is. On a first clutch half isn't bad.
3. clean water, a good cave where he can fan easily
4. about every month
5. to get them in spawning condition again add a small sliver of fish or seafood weekly.

In my experience it's not at all unusual to have twice the number of fry than you see at first.

This is hopefully going to be his future home. It is not quite finished as I will still add another layer of gravel.
