You were at Betta’s Pride? Armin has bintan sometimes, but which form he has changes every shipment. Any idea about what you’ve got?
I experience quite some agressive behaviour in females of my bintan-variants. They sometimes even bite the males.
I never use other additives. The leaves, peat and wood do their work good enough. In my betta strohi-tank I added phosphoric acid as experiment. This doesn’t do anything with humic but since they do not want to breed I tried lowering pH to 3,5. This doesn’t seem to do anything though. I believe it is the humic substance itself rather then pH lowering caused by it.
Off course you’re not going to be fired, I also questioned it. I normally keep blackwater fish in pure RO water, with leaves and peat added. When I didn’t use peat or leaves, the fish seemed to run out of salts and minerals. They didn’t colour up and looked sick. This quickly disappeared when I added oak leaves. It also disappeared a bit when I added plant nutrition, but not as good as humic, and it also raised the pH.
In tap water though, they do fine without humic or anything. But since they don’t breed in tap water I recommend using RO with humic acids. So if you want to keep them alive until you have a sufficient breeding tank I recommend using tap water, but as soon as possible get them an acidic blackwater tank for breeding.
This goes up for all fish I tried it with, including Apistogramma, Dicrossus(these did a lot better though), Betta, Pelvicachromis(this was by accident, didn’t intend to try them and they really didn’t like it!!) and Parosphromenus.
Welcome to the project!
Ruinemans occasionally has P. ornaticauda. Previously they used to import other forms as well, but since most species are hard to keep good in such conditions they stopped doing this. Only P. ornaticauda seems to do well.
If you want P. deissneri you better buy a ticket to Bangka, an island off Sumatra. This is the only known place you can get them. There is only one pair we know of, which seems hard to breed.
Utaka in Amersfoort has a bintan-variant at the moment. In this topic I put some pics of them.
P. sp. “blue line” isn’t exactly a species. It is just a name traders give their paros with blue fins, regardless of species. Fish bought as “blue line” mostly are bintan-variants. The bintan-complex consists of a few forms of which taxonomical status isn’t clear yet. Since most of them are rare in the hobby you could consider getting some if you can. You never know which variant you get, though.
But why do you want Parosphromenus?
I just noticed the male doesn’t stay in the cave anymore. He also ceased showing “sexy eyes” constantly, like he did the past days.
About cocnut caves not being ideal: they don’t have film canisters in the wild, do they? If a bunch of leaves is enough in the wild, a coconut should be fine too.
Thanks for the answer.
There is a layer of Ceratopteris in the tank. The paros I have don’t normally use shelter, even in tanks without floating plants. Also, the specimen in question didn’t show this kind of behaviour before given day. It swam around, mostly between some stones and pieces of wood, and displayed to the female when she came out of the Ceratopteris. That day he was constantly chasing her and kept flaring and dancing around her, so I was excited when the day after he stayed in his cave all the time.
I’ll keep watching them and looking for fry. I’ll pour some vinegar eels in every now and then just to be sure. The fry of one of my other bintan-forms seemed to greatly benefit from floating Ceratopteris and stay hidden in it, so I will keep looking in it.The male of the pair I separated is now defending a coconut shell. He stays in most of the time, but when the female approaches he darts out to display and flare to her. My other paro’s don’t use these kind of caves normally, so does it mean he is defending a nest? He has been doing this since 28 february. He is mostly peeking out the entrance, looks cool.
Also, how long do bintan-forms defend theit nest mostly?
Cool they spawned! It is a bintan-variant, impossible to tell which one exactly. It seems very similar to one of mine.
Parosphromenus‘s sister group, Betta, contains a lot of mouthbrooders. Some bubblenesting species are know to sometimes carry their eggs ot fry, and in B. brownorum some strains even really mouthbrood at certain conditions.
Since Parosphromenus and Betta are closely related it won’t surprise me if similar behaviour would also occur with paros.About the eggs being on the ground:
Perhaps the male isn’t experienced enough to correctly stick the eggs to the top of the canister.
