Re: Mogurnda cingulata

Hi, Thank you both for your info but I am not fully satisfied. From the biotope picture I see a water body with monotone gravel - my question is what are the niches for all these very similar fishes (same size, hunting the same pray)? With rainbow fishes for example, we see may be 2 species (of diff...

Re: Mogurnda cingulata

Hi Andi, great :D Do you know why there are so many Eleotridae/Butidae-species in this Mimika river (I assume this is not normal)? Are there so many different habitats or do they really share the same? I assume they are all eating the same kind of food/fish? Maybe some are day-active some night-acti...

Re: Melanotaenia sp. "Sungai Sungguer"

Seems my guess was correct, I just found the Sungai Sungguer on a map (look at approximately 1°25' S and 132°5' E):

Re: Melanotaenia sp. "Sungai Sungguer"

Hi Aileen, On facebook are two photos, from that I deduce it probably comes from the Indonesian part of New-Guinea, in special Birds Head peninsula. Probably it will be of the same size as other fish from that area. https://www.facebook.com/belowwater/photos/a.1401947900075284.1073741827.14015138767...

Re: Website Aquaticlife

Hi Adrian, I think there were some really good pages about the Chlamydogobius species / Hypseleotris / Mogurnda?. Since we are planning the topic "gobies and gudgeons" in our IRG "Regenbogenfisch" issue 1/2015 and I am one of the editors, I am simply looking for some comprehensiv...

Re: Biotope for dwarf neon rainbow fish (Melanotaenia preaco

Hi, M. praecox was found in the mamberano region in relatively quite waters like small backwaters etc. within rain forest not in the channels with flow (like Chilatherina fasciata). The water was rel. soft and tannic but clear. Not many waterplants in the natural biotope. Sandy ground probably with ...

Re: M. sp. "Ifaupan" is now M. flavipinnis

Hi,

To come to an end, it seems that the yellow rainbowfish from the Ifaupan (or Gam) River shown in the top post is now scientifically described as Melanotaenia flavipinnis.

Re: G pseudoincisus

Weber originally described G. incisus with a unique feature - confirmed in the 1980ies by Allen(?), that the scales are irregular ordered (and not in nice rows like with other rainbowfish). If this is still true, that should distinguish them (even as young fish) in particular to G. pseudoincisus? On...

Re: C. lorentzi

Yes, in theory the results/publications will be discussed within the academic world until one view will be accepted (even that can be wrong, see Albert Einstein because he was at that time too far ahead for his colleages) ... but in this case it is easier: if the only one or two existing experts in ...
