:cheer: – its all right, I understand your ‘condition’ 🙂 … and actually I realised, – we might have to work on a more detailed ‘guide’ for coming parents .. I couldnt find anywhere where it says something about how many days for hatching and so … here on the homepage. We should have a more precise guide. But feel free to ask any questions.
They will hatch in a couple of days. 4-6 days after they will be free swimming, – and then possibly stay in the cave some days, maybe a week more ..
But it varies a bit from male to male alsoI wouldnt worry about changing water right now, – in both ways actually. Normally I find that they do fine with lesser waterchanges also in periods, – its not as if you have a very ‘loaded’ tank producing lots of waste. But also, I have changed water not knowing that males were sitting in caves, and I didnt do any damage, – but still better wait a while.
🙂 yes, I agree, they are incredible. The males will most often stick to the cave as glue, and you can even lift it up with the male staying inside it. I will not recomend that though, – the male will stay as long as he can, – but might suddenly get scared and jump, or get stressed. But its amazing how ‘faithful’ he is.
If you dont get the small fry out this time, – I would still keep feeding if I were you, – you can never tell. Sometimes adult fish dont eat the fry, even they gobbel up moina 🙂 … or the fry is just amazingly good at hiding. I would not be surprised if you had two or three little parvulus appearing in two months time 🙂 ..When you place the cave, it is an advantage to test it before if you have a good look into it, – but be careful not to lift only one end of it up, as the bubblenest then could slide out. I often place the whole cave on something so that I have a good look in it.
I like the way you describe how he went for the bamboo, maybe thats worth while trying. Mine take mostly the clay cat-fish caves or the film cannister, – but I had a pair of linkeis using the same kind of flower pot as in your tank. They didnt mind.
Did the parvulus use the flower pot ?
I used one in one tank, and this is the one in which the fry did not stay after becoming freeswimming, I think it was too open. They still survived though, just didnt stay the normal period in the cave.
What about the air filter – have you made certain that no fry is going to be ‘sucked’ into it ?
I like your setup, I think its fine.
Just an update :
I realized my video of parvulus was set to private at youtube, so nobody was able to see it.
I have changed that now 🙂Hi again.
I would not use egg yolk fry food, as you say – it will pollute the water. And they wont take it I am pretty sure about that.
Once the fry is out of the cave, and once they themselves have no more eggyolk – you will loose sight of them totally. Which means you will not be able to target any feeding. They will dissappear into some of the dense areas of the tank, most likely at the bottom in the beginning, – they will also of course be hiding from other fish, so they are really invisible for probably about a month or two months.
And then … where to add food ?? :dry:
So in my opinion one needs to cultivate these infusorias and add to the tank, – and I dont think you need to worry about polluting the tank or other fish, even theres quite a big amount of infusoria.After about a week or so, you can already start adding things like microworms, and if you feed the other fish with artemis nauplia theres also a chance that the fry will feed on the tiniest of these.
So I would feed infusoria for about a week, then move to if possible, vineager ells or microworm for a week or two, then leave it to only be artemia – or of course you can change between these, but infusoria is only important in the very very beginning – they will move to other type food quick.
The tank size is okay, not overly too big. – and why dont you as calm as possible, when over the next days you have the chance, just net out one fish at the time and move the adults.. leave the cave and the male and move the other fish ? I think theres a better chance then.
That is really wonderful news, congratulation.
I find the parvenus a really energetic little fish so I am not surprised of the behaviour.Now you are in for a challenge though 🙂 – feeding the fry if they develop. And of course the other fish in the tank. I am not sure what you should do here. Moving the fry when they are free swimming is probably very difficult, they are very sensitive then. Is the tank too big ? Because otherwise you could catch the grown up fish immidiately after the fry has left the cave. They will hide at the bottom and not get hurt.
You may be surprised though that even with six grown up fish some fry might still survive.It sounds like you can look into the cave which is a real advantage, because then you can follow if the develop properly. The eggs will in a few days develop little larvaes hanging from each egg and these will develop over some days, – about a week altogether – at some point they will kind of turn to horizontal position just before becoming free swimming. Depending on the cave, they will either stay in this for some more days – or disappear out. I have one cave which is too ‘open’ and the fry dissappear immediately, but most times they stay.
You should think about food now, thats for sure. Do you have any experience with infusoria ?
I have some tiny infusoria which I keep as a culture, thats quite helpful because then I always have some ready, but there are ways to make infusoria fast. I could find some other peoples suggestions, but maybe there are some people here at the forum ??
I am not sure how to do this .. I have done it with putting a salat leave in boiled water, – it works, but I am not sure if there are better ways.
Artemia will be too big, – micro worms are also too big in the beginning. When you think of how small the fish are, well .. what do you think the fry will be .. 🙂 very small. Maybe vineager eels could be a food that could be taken, I have also used that.
You need to start it right away if you are making infusorie and you need to think how big the tank is – I think you cannot really ‘target’ the fry and feed a little bit each day, – you need to feed in abundance in order for any little tiny fry to find the food.Have you got some dense areas of the tank where theres a lot of javamos or some peat which the fry can hide in ? I think this is important.
But tell us more about the exact tank size and how the eggs are developing …
Really exciting news !
As you can see in the video clip of mine, its also around dinner time this male is ‘dansing’ or flashing, but its the same, – no not directly spawning but courtship behaviour it is. Impressing the females, making them interested. And probably also stimulating the female maturation.
And I am sure your male is big enough. They are small, I have a small male like yours two, same size almost, he has eggs now. They might still continue to grow though, but it sounds like he is starting to feel like a grown up fish 🙂
But you may be right, – its the beginning of courtship behaviour, they may not be quite old enough, the females may not be there yet.Heres a little parvulus ‘snake’ dance …
It is not always easy to see the red spots – and difficult to photograph them, – but they are beautiful in the flash light.
[video]http://http://youtu.be/fEQFNzLQPSM[/video]I would like to add something.
You asked in the first post why the male is not staying with the cave all the time ?
I think that that really is because he is loosing ‘interest’ in the eggs because it is not a successfull spawning as I mentioned above. Its quite typical behaviour of the male to then not stay with the eggs.
The eggs which stick to the ceiling will make him stay underneath these totally uninterrupted, but as they are not as they ‘should’ be according to his instinct he is wandering off and not really certain what to do with the eggs .. untill they disappear and he will start another nest and another spawning 🙂When the eggs are ‘normal’ and staying in the nest, most males are extremely stabile and wont leave the cave at all.
I am afraid the spawning this time is what you could consider ‘not so successfull’ – I have experienced the same situation as you some times, – where the eggs does not stick to the ceiling, – and these eggs will not develop. They will most likely be gone by tomorrow. The male was trying to either get them to sit at the ceiling, or indeed he could have been eating them.
What happens is quite ‘normal’. The spawning is not succesfull when the eggs lye at the ground, so the parent fish give it up after a little bit, and they then eat the eggs. The nutritional value of the eggs is then preserved in the fish, meaning its not wasted. And the fish will produce eggs again.If you have another tank I would definitely say you should get the male and female paro in that, – they will spawn again shortly after, – and there a much bigger chance of success then, also for the eggs to actually develop. And say you got the eggs to develop, and wanted to feed small fish 🙂 .. I will tell you the paro offspring is so small you have – in a bigger tank – no chance of feeding them. Or rather you cannot find them and they cannot find the food.
The food you need for these small ones is not artemia nauplia thats too big. You need some kind of infusoria, or vineager eels.
In a small tank its much easier to induce a milieu which support infusoria growth, and its easier to ‘target’ the small fish.
But you dont see them. I have just yesterday discovered that one of my parvulus pairs had offspring, – they are at least a couple of months old and I have not seen them before now. And trust me, I have been checking the tank with a flash light often enough. But you simply dont see them.Congratulation with the spawning.
The male is taking the eggs in the mouth as he attempts to get these to sit in the nest. They probably fell down – where they are now lying on the bottom of the cave – and he is trying to get them to stick in the nest. Parosphromenus are in no way mouthbrooders 😉
That the eggs doesn’t stick to the ceiling of the cave has to do with the water and microsiemens not being low enough, – what is your water quality in that regard ?It seems your paros are willing to spawn – but being together with chocolate gouramies there will not be any offspring growing up.
It doesnt matter whether the cave is at the bottom or floating, – paros often choose caves situated at the bottom as well.The image does not load from this page. Its uploaded in your post, but theres something going on with SeriouslyFish.com which does not seem to allow any search to go through.
If you searched the internet / images – using ‘parosphromenus deissneri seriouslyFish’ as searchwords, I am sure its the first photo that comes up ???
I dont know anything about the history – but I am certain if anything this would be a p. bintan. Try have a look in the species gallery.OH .. :S correction, – the image now uploaded fine. That is the image I found through my search also. I will leave my comment anyway, in case the upload is only sometimes..
😛 I am gonna risk my reputation here (just kidding of course) .. but I think I would disagree that this should be a female …
Well, well, we shouldnt of course make this a competition, – it just shows you how difficult it really is 😉
And really, I am open to the fact that it may still be, – body shape and so reminds of a female – but then, I would have learned something new, – that some females can show these marks, which we normally consider to be signs of a male. Or its a species where both male and female show marks like this ?Martin Hallmann of course has years more experience than I, so maybe he is right. However, the one fish that were on the photo in post 1782 – I would myself feel certain that that was a male. I have never seen a female with that clear pattern in the caudal fin.
But theres no point in discussing this really .. its always a bit difficult, and I dont want to claim I know better than Martin 🙂 ..
I try to give the advice as good as I can from the images you bring. I mentioned in one of my first answers here to you that I thought most fish looked female, – so maybe they are after all.
But the photo in 1782 ?I would hope for you that its a male .. 🙂
