Thanks Helene – I had not even seen that page before, how did I miss such a big part of the site 🙂
I will have a good look through this section.
Helene,
Thank you for your answer and photo’s.
I agree with you my fish look very much like yours.
However, what is spec. sentang? I don’t see that listed in the Species list on the site.
Any of the experts here can help with the ID of these fish, hopefully this and the previous video can help identify them.
I now have about 10 free swimming fry from these growing on in a tank of their own.
Latest video of a juvenile P filamentosus that I found in the tank with the adults.
This one is about 12-15mm long and has obviously been surviving in the tank with the adults for quite a while.
Tonight I spotted other youngsters in with the adults from at least 2 more separate broods. I am very surprised at how many are surviving in with the adults.
Thanks Helene and Peter for your comments.
I am pretty sure now that they are not P deissneri.
I have got a better video of the male tending to his fry, this will hopefully allow someone better than me to say what Paro this one is. I ahve removed the fry from the male today into a rearing tank of their own. The male has been an excellent father and has hardly left the cave for more than a few seconds the whole time since the eggs were laid.
[video]http://http://www.youtube.com/watch?v=6CT5tEy94AI&feature=youtu.be[/video]I mentioned in one of my earlier posts that I have now seen at least 7 good sized fry from the 14 that I put into the rearing container, I am now sure there are at least 10.
I also spotted lots of fry, at least 7 or 8 in the tank with the adults, these ones I would estimate are about 7-10 days free swimming, I was very surprised to see them in the adults tank swimming without any fear of being eaten by the parents.
Hi Helene,
Thanks for the link, I often order food from TA Aquaculture but have never noticed the rotifer cultures.
In one of my earlier posts I enquired how I can post an actual photo, or video, just like you do, rather than a link which is all I seem to be able to post.
Thanks Tedsomd, the water parameters for my P filamentosus are kH 0, pH 4.0-4.5, temperature 25C, TDS 25-50.
Very good photo’s Martin and beautiful fish.
Similar to Helene I also particularly like the P langgam.
I managed to get a short video today of one of the young P filamentosus.
Up until today I had only seen 2 together, but I have seen at least 7 at the same time during today.
Hi Peter,
Thanks for your message.
I now slowly get the impression that the dark period after may end …
Let’s hope so. There are a few of us now trying to do our bit with Paro’s, time will tell if we can be successful.
on the yeast method: Nevertheless I am cautious because I don’t want to infer yeast into my Paro-tanks …
Me neither, its one of the reasons I stopped using yeast in my paramecium cultures.
on the visibility of young fry: After free swimming young Paro-fry are mostly not visible at all, but about one to three weeks later one sees more and more. Of course, some parents are aggressive against their young, but not all. One has to try it out. The youngest often hide in leaves on the ground, later on in swimming plants on the surface.
So far I have seen only one fry (the photo I posted), hopefully there are more that are hiding.
on the name: It’s filamentosus (not -um, at least in the original description).
Thanks for pointing that out. I have changed reference to that on any of my posts where I can.
Hi Helene,
Thank you for your message, it certainly helps seeing a photo of the bottle you are using etc. I will have to try it.
I feed my paramecium an egglayer fry food liquid “Liquifry No 1” a couple of drops per day for a 2 litre culture.
This morning I was lucky enough to see one of my fry for long enough to take a poor photo, but at least I now know that at least one is still surviving.
On another note, how can I get my photo’s to appear in the message rather than appearing as an attachment that people have to click on to open? Your help would be appreciated.
Hi Peter,
Many thanks for your reply.
I think that Allan likes to see people continuing his work with Paros in Britain. For he did it for many years with great success and it ended abruptly. It’s really a pity for the British Paro scene (and the continental, too)!
It is a real shame based on what I hear from you and from others too, certainly the time I spent with him was very useful.
Surely, the filter sponge will produce quite a lot of edible organisms for the young fish.
Its something I have done often with Corydoras fry, it seems to get them off to a good start.
I know the first from Paramecium; it does work with vinegar eels, too. Fill the eel-loaden vinegar in a bottle with long narrow bottleneck (or breed them there already)so that the narrow bottleneck remains partly free. Then put a pad of cotton-wool in it with contact to the vinegar. And then fill the rest of the bottleneck gently with water. Two hours later you can harvest the eels by a pipette and feed them to the fish.
I have heard of this one but never tried it yet, I will have to give it a go. I have never heard of it for paramecium though. I just use a turkey baster to take the paramecium and the water they grow in and put it direct into the fry tank.
The second method is similar to the harvesting of micro: use a small amount of yeast in a bottleneck to attract the eels. After a while they creep out of the vinegar on the blank insides of the neck. You can harvest them with a fine brush.
This one I have never heard of for vinegar eels, it sounds like it would be quite tricky but also could be worth a try if the first method you have noted does not yield good results.
Today is the first day that I have seen one or two of the fry in their rearing tank, but I only got a fleeting glance at them as they swam off into the leaf litter.
Hi Peter,
Thanks for your reply. Unfortunately my access to Allan Brown was only for an hour or so at the meeting last weekend.
I currently dont have rotifers – at least not a pure rotifer only culture. I am sure that water/debris from a mature healthy sponge filter will provide many “rotifer like” organisms, at least I hope so.
I do have a tin (actually 4, 500g tins) of the very small California type BBS eggs but have not yet opened the 1st one as I am just finishing my last tin of previous bigger BBS eggs. I may open it and hatch some in about a weeks time when the fry should be able to eat this.
Vinegar eels is a live food that I do have a culture of, but have never fed it to my fish as I have yet to come across a god method for harvesting them – any tips?
Regards
Paul
