Is my payara going to be ok in a ph of 6? I am changing the tank over to a well planted tank with CO2 injection and tons of plants. The ph is settling down at around 6 and i am wondering if this is going to be ok for him if i can keep it stable here.

Also if anyone know about redtail barracudas he is in the tank with the same ph as well. is he going to be ok at this ph?
 
The all Will be just fine as long as you acclimate them down to that ph.

Like if you take them from a 8PH and dump them in the 6 PH they will get shocked.

Most amazon species due well at low ph's. Because that is what there native waters are.
 
mine live in 6.5-6.8 (not disputing 6.0 wouldnt work) Im not sure, but water's got to be very clean at any ph. payaras have thin skin and cudas get fin rot easy.

hybrid - i would have thought that in high moving rivers, even in densly planted amazon would be higher than this?
 
Sorry I should have said more. Oops

I read in a discus book long ago that in some area's of the amazon that the Ph would drop below 5 because of the lack of flow and all the decaying organic matter.

So that was more than likely talking about the flooded area's during the rainy season where the discus congregate to breed and such.


So maybe the Ph would be higher in the rapids and stronger parts of the river because of the agitation.


Hmm time for some research.
 
Here we go


Three major types of water are found in the Amazon each with its own clarity and acidity (pH). Black-water and clear-water are the most ancient water types. Black-water rivers drain mostly forest and savannah areas on extremely poor sandy soils (i.e., Rio Negro and many rivers in the central Amazon Basin draining relatively small interfluves with sandy soils) having coca-cola coloured water stained with folic acids causing pH values as low as 3-4. Clear-water rivers drain predominantly pre-Cambrian rocky areas of the Brazilian Shield (i.e., Tapajós, Xingú and Aripuana Rivers) and Guayanan Shield (i.e., Marauiá, Padauarí, Demeni and Branco Rivers, and all rivers in the Guianas flowing south-northwards into the Caribbean Sea). Clear-water rivers have crystal-clear water most of the year and account for pH values of around 7. White-water rivers always drain regions with fertile soils of volcanic origin (Amazonas Solimões, Madeira, Purús, Juruá and Javarí Rivers) and carry fertile silt that makes the water light brown muddy and silty accounting for pH values of 7-8.


So if the fish comes from the rio negro then a ph of around 4 is common and if it comes from the clearer regions of amazonia then a ph of 7 is normal.

Here is the link to the full story.

so i think we are going to be fine at around 6 then?

i love the research and the info. That is really good stuff. I bet that for the payara through to ph is usually right in between since they are in fast moving water that is no where near clear. so I would guess that their natural ph is somewhere between 7 and 7.5. Not a big jump down to 6.

but, there probably are some species of payara found in slower moving water where the ph is around 5-6.

similar for the barracuda. im sure the barracuda is in slower moving water of the amazon especially since the payara can easily eat one without any probalem what so ever and would most likely love one as a snack.

so the barracuda is probably ok down to 5.

They absolutely have been aclimated slowly and the water is so clean.

Thanks guys.
 
I keep mine at 8 and the water HARD.

Why? cause that's what comes out of the tap here, I don't use chem. unless it's to medicate.

I do change the water about 25% every week.

Always Got good color and VERY HEALTHY fish.
