P. tweediei (ruinemans 2013) questions!!!

Congratulations, Rafael, – thats great to hear that they have spawned.

My answer to your question is another question: Why do you not think about moving the parents ??

I never move the fry, – I know you can do it, but I think it takes some practice and skill. At whatever stage the egggs or fry are very vulnerable to change in water, or to movements. I imagine it is really difficult to move the tubes or caves without eggs or fry slipping out.

I would always move the parents. To catch the female – with a little practice and a little patience should not be too difficult. I would catch her out first. Leave the male to guard the nest and when all fry has left move the male.
If you worry about moving and catching, leave both parents and keep an eye on when the fry is beginning to leave the cave. And then just catch the parents. Even if you create a turmoil catching, the fry will just seek cover somewhere, – they will survive.

That is my advice anyway, dont move the fry, move the parents.

Hi Rapael.

Congratulations on the tweediei spawning.

When we were at Bernds fish room, he demonstrated how he moves the nest. I don’t know if you saw this?

Basically he used a small plastic tub, maybe 5cm deep and larger than the cave itself. He sank this in the aquarium to fill it with water, lifted the cave carefully into it, and removed the whole thing still full of water to his rearing aquarium.

I have done this and found it very successful. When I see eggs in a nest,I set up a small (5lt) aquarium with lots of java moss, and some old oak leaves from the parents aquarium. When the fry have darkened and are moving around in the cave, I remove it and the fry as described above.
I find it easier to control the amount of food in this small aquarium, anything uneaten can be seen and removed easily.

I have been successful by removing the parents as Helene suggests, but I personally prefer to remove the nest.

There doesn’t appear to be a right or wrong way, just personal preference.

Hope this helps, good luck.

It has been written within this forum by people far more experienced at breeding Parosphromenus than myself, that the male should always be left to tend to the nest.
The eggs will not hatch without his care. The young fry also need his care to develop in the first few days. Once they turn dark they appear to be strong enough to fend for themselves. I start feeding with small food ( banana worms) as soon as I move the nest.

In my experience, they darken and leave the nest within 3 to 5 days. I don’t know if this is dependant on what species, or other factors.

So Rafael, keep a close eye on their development , it may be quicker than you think.

As we told at other places here in the website of the P-P or in the Finke-Hallmann-book, there are many different methods that have proven to be successful. The Bussler-method of taking the cave with the eggs or the young fry is only one, you can do just the opposite (take the adults out) or even leave everything at its place. The latter one is the most easy and interesting method, but a bit risky as long you do not know how the special pair behaves. But one should test that out. If they spawned once, they will spawn a second and a third time if good conditions prevail. It may go on for weeks. However: Do not think this will go on for months, and thnking next year they will spawn as they did this one maybe wrong. The causes why this may not be the case are not fully clear by now. It is a good advice to grow some offspring up as early as possible.

If you separate the clutch from the father, you renounce of the father’s care for the eggs and later on his care for the young larvae. This is by no means without meaning, especially in the small tank with stagnant water and nearly always many germs. Mostly, a part of the eggs fail to develop, become white and die and infect others. This is prevented by the father’s care very efficiently. So, Bernd’s method is possible, but do not part them too early.

Now Bernd Bussler reports once on the subject.
The eggs of Paros have little change to evolve if they are not cared for by their parents. I really have tried everything, but from eggs whom I removed from their parents, I could only occasionally bring Jungparos to slip
When the boy fishes leave the nest is strongly dependent on the temperature at me about 26 ° C, which lasts 4 to 5 days, but I’ll take the den with pups out earlier. If they turn dark and no longer depend foam nest. There are of course other ways, for example, leave everything in the aquarium with their parents or take out the parents, both methods work, survive it definitely enough juveniles.
My method (Bussler method) I’m at as many kittens to get and move on to. Makes you not worry so much, as the main thing you have ever bred, showing the grooming her your Paros properly and if everyone repeatedly rears few Jungparos year we have done everything right and can get this wonderful little fish. 🙂
