@Peter
Thank you. I was sceptical when Anton told me, and told him we all thought they do have the labyrinth. He said he dissected multiple species but didn’t find a labyrinth. Perhaps the size of the organ differs between species?@Peter
Not that I don’t believe you, but did you see the organ yourself or did you read it in a scientific article?My quindecim] once did this after I put in too much beech leaves.
According to Anton Lamboj (an ichtyologist) paros do not possess a labyrinth organ, in contrast to all other Macropodusinae. He dissected quite some of them but did not find any labyrinth organ. He said it was severely reduced also in Malpulutta, and to a lesser extent in Trichopsis, while Pseudosphromenus and Macropodus had an okay one, and Betta a good organ.
I only use a filter when I have really big amounts of leaves, to prevent oxygen deprivation. Otherwise a tank without too much fish really doesn’t need a filter. Out of my nine tanks only two have a filter running at the moment.
I would suggest you to take out most of the leaves, but don’t boil the rest. You’ll destroy the cell structure, making decomposition a lot easier. Leave in a part of the leaves and add an air pump. Wait for a week or so and put in more leaves. Repeat until all leaves are added, and then remove the air pump.
Ah, ok. Then your idea sounds good.
Fortunately, those species are not only easy, but also very beautiful!
You could refer to it as you want, but linkei is a lot easier (and scientifically correct!) than pearl licorice gourami. It seems a bit useless to make up a new name while there is already a perfectly good one around…
I would say, move those Cryptos and Taxiphyllum to the small tank and make it a permanent paro-tank. In the menu on the left of the page you can find a guide to setting up such a tank.
What species are you planning to keep? There are slight differences in size, behaviour, and tolerance, so for giving accurate tank-setup descriptions it would help if you’d mind the species in question.
That would probably work, although it is unnecessary to remove them from the small tank. Most breeders keep and breed their fish in the same small tank.
By the way, most here are German, Dutch or other non-‘Muricans, so use of the metric system is preferred!
Depends on your tank’s height. The layer can be as thick as you want it to be, as long as there is enough space left for the fish to live.
They will do fine for two weeks without feeding too, if necessary.
Paros last extremely long for some reason. I think they find small organisms in their tank. I have a pair which do not get skinnier, even though I haven’t fed them for weeks now. (I don’t recommend this with rare species! These particular fish are a common form)These clearly are Betta, probably splendens species group. Which one is’t visible, but it isn’t smaragdina, mahachaiensis or stiktos. Looking at the red seam in the caudal and the blotch in the tip of the anal fin (third picture), my guess would be imbellis.
Make some better pictures, preferably in nuptial colouration.
Interesting. I wonder what will come out, if anything at all. If they happen to produce viable fry, they problably won’t be fertile, or reduced. Let’s see what pops up!
From these picures all I can say is they aren’t deissneri. You have to wait for them to show nuptial colouration and pose for a photo really good.
This seems to be a pair, altough here too, the same as above applies.
P. ornaticauda is available regularly at Ruinemans. Always in quite large numbers. They seem to know where to catch them…
@Steff
These are the same fish, from the same Ruinemans shipment. I looked at them when they arrived, and because of the amount of blue in the fins, I told them it could be alfredi. They now offer them as such. It will probably be switched to tweediei soon.
