If you look at the caudal fin, has a dark lower lobe, while has a dark distal margin, like your fish.It might be the L050, why do you think it is that one? I was also thinking it kinda looked like an L166.

Re: Diversity and community structure of rapids-dwelling fishes of the Xingu River
I would assume that doing another survey today vs 2014 would already be showing changes in species abundances. Doing one once the dam has been fully operational over a couple of seasons should reveal that a lot of species are completely gone or are almost impossible to find in any significant numbe...

Re: How to distinguish LDA007 (L114) from L273?
I recall that full genome sequencing has been done on Lake Victoria cichlids, addressing similar issues, including genetics of color variations. So there is know-how how to do this in fish. Oh sure, the methods and the expertise exist, but the problem is cash. Sequencing this quantity of data is ex...

Re: I do not have any idea of what kind of catfish is this
I'm looking at the COF and at Fishbase - Oddly, COF lists Carlarius latiscutatus as valid and Arius latiscutatus as a synonym. But Fishbase lists them the other way around, with Arius being valid and Carlarius being the synonym. What to do with that?!? Have a read of this: http://www.fishbase.org/N...

Re: Diversity and community structure of rapids-dwelling fishes of the Xingu River
This was not a "before and after the dam" study. It was about whether the fish communities differed between the different zones of the river.What makes things worse, imo, is that the before and after studies were done pretty close together time wise.

Re: How to distinguish LDA007 (L114) from L273?
Wonder why genetics are not being used for to aid species description? It is, slowly, but it's not always as simple as you make out. Where you'd think that DNA is most useful---i.e. in cases like the complexes of closely related species or lots of variation---turns out that DNA can pretty ambiguous...

Re: New RO machine for L121 and cories, need help
My advice: do not overthink, do not tinker, do not measure parameters obsessively (this causes overthinking). Just mix your RO water 80%/20% with your tapwater. This will give you nice soft water with a little buffering capacity. Change the water regularly to keep things stable. Exact pH is not impo...

Re: L134: Possible Ich/velvet, tail wagging on every pleco?
Velvet can be treated with malachite green, formalin, copper sulphate, or acriflavine. Not sure which is best, but bear in mind that formalin will wipe out your biological filter, and copper sulphate can be very toxic at low KH. Seachem Cupramine looks like a good option though for velvet if you can...

Be sure to act fast. It's lethal in very sort space of time. Slowly raise the temp up to 35C over about 12 hours, add massive amounts of aeration, dose with malachite green / formalin medication, and remove all driftwood (organic material deactivates the meds). Every day do an 80% water change and r...

Re: L134: Possible Ich/velvet, tail wagging on every pleco?
I'd say the majority of suspected ich cases in plecos are actually velvet. Ich is characterised by large, sparse, regularly round white spots. Velvet is generally a dense covering of irregularly sized small yellowy blobs. Ich https://fishcare.info/wp-content/uploads/2018/03/treat-ichthyophthirius-mu...

Cracking fish. As jac says these are true Pseudohemiodon apithanos. The marbled one has a rounded rather than triangular head.

Re: Ideas on setting up and maintaining a black water tank
In a tank with lots of bogwood and using rainwater, the pH will naturally drop low. Maybe a few alder cones added would help too.
Just treat it normally, but the key is to do smaller more regular water changes to keep the tank stable, maybe no more than 10-20% at a time.
