I think there are some good explanations here as to what could have happened, – and perhaps it is true that theres no male in there, – and it happened for some other reason.
But just one thought which I had is also, that if there were indeed another male in the tank, – the second male would likely be a lot more subdued because the other one was dominant.
I do not always find linkei to be that easy. As a matter of fact, just 5 minuttes ago I checked a tank in which I had one grown male with a grown up fry which I was certain was a female. Well, its not :whistle: … I just realized that a moment ago, its a young maleWell 🙂 .. but it is probably two females in your tank as you say 😉
Your study of the eggs are amazing, very interesting
:unsure: hmm…
If you have got a paro swimming out of a cave, – this to me indicates that theres ‘something’ going on. Normally the cave is the males property, and I would actually say I rarely see females go into a cave unless somehow in relation to spawning or a male inviting her. So if you have one of the fishes going in and out of the cave, – ? … are you quite sure you have two females then ?
The eggs look like paro eggs for sure. And it does happen with some fish who are either unexperienced or perhaps it can also be in stressing situations, – that spawning is attempted, but the airbubble nest is not good enough – or the fish hasnt learned the tecnic or … somehow the material of the cave is difficult for the eggs to stick on to … and then they roll out of the cave.
I have had it happen a few times.But to me it is strange when you dont have a male in the tank. I do not think that the female will give off eggs with no male in the tank
Oh, thats very sad to hear. But it can happen and there doesnt seem to be a good answer since the two other fish seems fine.
And its not unusual to not find the male, this happens too. Sometimes you find – other times they just dissappear.
He couldnt have jumped out ? Or hid in something which you took out of the tank ?I am very sorry for the loss, expecially because you did a great effort to get them, and it was not that easy for you ..
With paros – a dissappearing male is more often meaning that he is hiding somewhere in a cave, – either with or without eggs.
Of course as Dorothee says, its never 100 procent, – but I have often worried for males that I had not seen for many days, and found out that he was indeed occupied with something else. They tend to simply ‘dissappear’ and I dont see them eat either for long periods.One thing I would like to ask you about your tank is the amount of ketapang leaves ?
Normally, – depending on the quality I would not put much more than one in a small tank, they can be quite strong in the way they influence ph.
I dont think its a problem, – and perhaps some of the leaves are other kind of leaves, I cannot really tell. Just thought I would mention it.Yes, Jit, – I actually thought about that when saying that about the trichopsis vittatus, – because I do know that they are much more adabtable and can perhaps be a threath this way, and I wasnt really sure about what their presence there meant.
So thank you for pointing that out.I like the fish as fish, but I am sure they can be a problem under certain conditions, – which you are pointing out.
Thanks for posting the two extra photos, its very informative to see this site of it too.
Thank you so much, – it is really interesting to see photos from the areas. Can I use the photos for uploading somewhere at the homepage (probably at the species articles ) ??
Its sad about the Sedili area, – but I understand it could be because of the water level and hopefully it could change.
Nice to also see the tricopsis vittatus, – I have a big 325 liters with a mixed asian population, among these some tricopsis vittatus, – they are even breeding in there, which is quite well done. I guess they scare everyone with their little noises 🙂 ..You are very welcome here in the forum, Lawrence. Its a pleasure to have someone here who has been travelling in those areas, – and as we already spoke about, very interesting with the fish you brought back with you.
I have uploaded the photo of the p.tweediei in the species article of P.tweediei.I was thinking the same thing, actually. 🙂
Also because as I remember yours seemed to have much more reddish hue in the fins – at least in those first photos.Since there doesnt seem to be more answers I thought I would try to look into the different books I have.
But I dont get any nearer. If you are looking in Horst Linkes book also, then I understand why you mention sp.sentang also. The photo of this particular fish resembles yours a lot too.I think the reality is that when we are talking about this group of paros, – clearly fish in the p. bintan ‘group’ – there really is a limit to how accurate it is possible to id them unless we know precisely where they come from locally. This could have made it possible. But without it it may be simply not possible.
I am no expert on this (keep saying this) – but I am learning that the classification of the different paro ‘species’ may not always be that accurate or definite. Within the bintan group of paros there are many variations that are very close, – and to actually think that they are all seperate species just not yet fully described is wrong. We simply may not know how these different sp.’s are connected (for example sp. sentang, sp.blue line, sp.dua etc) I would refer you to read Peters remarks in this thread (the last post) as it says something about this particular problem with the P.bintan species.https://parosphromenus-project.org/en/forum/13-Trade/1583-p-bintan.html?start=6
Actually I think this is an important issue, which I would propose to Peter Finke that if possible someone should talk about this at the international meeting in Hamburg in september.
Or we could also have a written article about it on this homepage perhaps.
For people with a long historie of paro keeping it may have been part of their education, – for me as someone who entered this not that long ago, – it is only now becoming apparently important to understand. And I think many people are desperately often trying to identify the fish they buy in shops, – thinking that there have to be one rigth answer to it.If I had the means to study this scientifically I would 🙂 … but unfortunately this probably means you have to be a biologist or something. Too late 🙂
To me it seems totally impossible to determine if your fish is more likely P.bintan, P.sp. sentang, P.sp. blue line or perhaps even P.sp. dua. But it does belong in the P. bintan groupI dont think it has ever happened to me before, – and I think the reason it happened is because this 60 liter tank has a lot more lightening than the other tanks I have, and therefore produce an extremely thick cover of salvinia natans. (at some point it was literally a couple of cm thick). This way the tank floor is very dark still, and I am sure then the fry seek up in the cover of the plants.
For this reason of course I have a tendency to use this tank for supplying other tanks with more floating plants.
Normally though I would ‘shake’ plants like this well before lifting them out of the tank, – I think I must have forgotten this.
I would not worry under normal conditions, – and at least now I would still use excess plants, but I would be very careful to shake it well before taking it out.
But I will definitely keep this in mind as a potential ‘danger’ when transferring plants between tanks.I have a little embarrasing story about linkei fry :blush:
I have this 60 liter with some adult linkei, and obviously it now shows that there are many fry in there, yesterday I counted more than 10. This tank has a very thick layer of salvinia natans, and sometimes I take a little from there and put in other tanks.
I also have a little 12 liter with some tweediei offspring in – they are about 4 months old. Yesterday when I looked in there very big is my surprise when I see two very clearly linkei fry swimming happily around :blink: …
I assume they have travelled via the salvinia natans. I am very happy that this happened with linkei fry which is clearly different from other fry…
I have checked other tanks, but have not seen more.I will be very careful in the future when I take floating plants from one tank to the other
To be honest I think that it would not make so much sense to use the conditions to determine anything regarding species, as all of those which would be possible identification would be living in areas not that wide apart, – and they would probably all experience the same conditons, or the same fluctuation conditions, – such as higher temperature at times etc.
I can see your point regarding sp. dua, – I am unable to determine that.
I would doubt about sp. sentang though. The colour band seems to me to be less broad when we are talking about sp. sentang.Hi Yankadi.
I have no experience with hyalella and paros, – but regarding what you mention about a section on forum, – if you look at the menupoint weblinks (left on the frontpage)you can see that we have tried to gather links to places where you can buy life food cultures in different countries.
If you have any other good sources or places where someone who is looking for live food cultures can buy, or even find information, – you are very welcome to write this to me.
I will add this to the link section thenThis is an exellent photo of the male.
There is no doubt in my mind that it is resembling very very much of the species which here is called spec. blue line.
I hope Peter Finke will come around and give his opinion regarding this particular photo. I would ask you permission to use the photo (when we are a bit more certain). It would be a great contribution to our attempt at documenting species as well as different variants etc.
