Ivanacara bimaculata is this the correct name now?

[Mazan]

Just wondering, as the local fish shop owner told me he might get some of these. When I googled it quickly only Nannacara bimaculata came up at first. Later I did find a reference to ivanacara bimaculata, I assume this is the most up to date name?

There does not seem to be much information around about this fish...

If you go by Uwe Römer/Ingo Hahn (2006), I. adoteka and I. bimaculata should be recognized. While for I. adoteka Ivanacara has been fairly established for some years now, most still say Nannacara bimaculata. That's for the hobby community. In the scientific community Ivanacara seems not to be recognized widely at all.

That is interesting, no wonder I could not find anything on google scholar!

These infos are freely available on Wikipedia and fishbase. Rest is observation.
Here's a link you might find interesting.

Has anyone here actually kept N. (or I.) bimaculata? Just wondering, I could find very little information on this species.

 

[MacZ]

Seems almost all pictures of that species you find are at least 10 years old. Not a good sign.

 

[Mazan]

Yes, I did find a brief video on YouTube from earlier this year. But it certainly does not seem to be a commonly available or kept species. I am surprised our local guy says he can get them…

I'd be suspicious.

I'd be suspicious.

Yes I am. I did find a short piece about them in Turkish....didnt say very much though.

 

[MacZ]

If he can get I. adoteka I'd say I believe him, but I. bimaculata... doubt it very much. If you're lucky he'll get you I. adoteka. If not you end up with any of the remaining Nannacara species.

You are probably right, he did say they would be very expensive, but I. adoketa would be as well....I didn't ask how much though...I think he said he was getting them from Asia so not wild caught... I will try to find out more from him. I was wondering since moving my larger cichlids I now have a 240l tank with just two small plecos in it, and even those could actually go in other tanks...

If that's the case I'd probably pass.

 

[Mazan]

I don't know, it is so rare even to get Apistogramma here. He is getting some A. cacatuoides soon but they are also from Asia, and they are plain grey with yellow tails, not sure what type they are called but I am not keen on them. If he did get I. adoteka I would be interested in those too, or maybe even any Nannacara, not seen any here at all. I will try to find out more.

N. (I.) bimaculatus occurs so far up the Potaro & Essequibo drainages that no commercial collector would be willing to spend the money to travel that far just to collect fish for sale. Fish hobbyist, however, might. TomC & I did when looking for A. cf. payaminonis (= A. wolli). Many days and $800 in fuel + additional costs later we brought back less than 2 dozen specimens. Definitely not commercially feasable, but then we are 2 crazy apistophiles. I would be more skeptical if they we wild-caught, but maybe some other crazy hobbyist decided to spend the time and money to go find them. Photos would be helpful (look for a white anal patch).

 

[Mazan]

I will try to get some more information from the fish shop guy. Maybe he can get some real photos from the distributers. I can't imagine that they are bred on a large scale in Asia, or they would be more commonly available, so maybe (if they really are this species) they are not too far removed from the wild ones...

@Mike Wise please can you tell me something about the habitat you found them in? Was it blackwater? Any plants etc? I was looking for this sort of information (just in case), and have not been able to find anything other than the river drainages they occur in.

Mazan, my trip was to collect A. wolli in Peru. The only recent report about N, (I.) bimaculata that I know about is in Romer's Cichlid Atas 1. Romer reports that Franz Vermeulin collected the species in 1997. Vermeulin told Romer that the water was similar to that of I. adoketa: blackwater, very acidic (<pH 5.5) and extremely soft (almost no hardness of any kind at all). There are no known reports of successful reproduction that I know about.

Interesting, thank you.

This Swede seems to have collected them in 2019, and bred them just a few months ago ...

That makes sense as I found a short video from January this year, the author's name sounded Scandinavian. Just shots of the fish, no info on the video. Don't know how I missed that post in this forum, thanks.

Your guy should ask the supplier for photos. He should also give you price estimates if they were to be ordered. Then go from there IF you're still interested. If the supplier cannot or will not send pics when asked, I'd pass.
