Re: What do you guys do to lower pH?

First question is why do you need to lower pH? Then its what are the start:finish parameters you wish to achieve, notably the tap, tank and desired levels. I find may people overestimate the importance of ph compared to the hardness of the water, a factor not helped by false assumption that it will ...

Re: Well I never!...L205 is NOT Peckoltia brevis!

Thanks for the reply Jools.

Re: First pleco selection for planted tank

So suddenly it is possible to have river systems in the Amazon basin that are at different temperatures, and now try extending the principle to the systems that lead to this point.

May sound obvious but have you tried searching by size? Also worth ensuring you refine it as Loricariidae only, and maybe order by number of keepers to weed out the many zeros that indicate species you are unlikely to be able to source anyway. ...and then just trawl through the pix until you spot wh...

Re: First pleco selection for planted tank

It is perfectly feasible that the temperature is very different in sections of such a long and varied drainage system. No, not really. The lowland Amazon region has a pretty homogeneous climate. The air temperature rarely drops below 24C. L205 can be found well outside the region as shown in the ma...

Re: First pleco selection for planted tank

That website you linked to says the Rio Negro is 22C, which is very incorrect. It's more like 32C, but that could have been a simple typo. It's correct that the Amazon River is about 28C. This is the same for other similar rivers I have been to, such as the Rio Madeira and the Rio Japurá, so why wo...

Re: First pleco selection for planted tank

I see no reason to boil the fish for a couple of months It's not "boiling" them, it's keeping them at the temperature at which they are found in the wild. They will be out of condition and malnourished after import, so the metabolic rate needs to get back to normal so they can start eatin...

79f too cold for Peckoltia? I think that after they have settled down, the temperature could be reduced slightly, but if I were trying to acclimate them to a new tank after the stress of importation and retail, I would keep it at about 29C, at least for the first couple of months. 22C is a temperat...

Re: moonlight lighting any use/good?

My Peckoltia also react to red light, albeit much less so than even dim white light. I have also ruled out that they are reacting simply to my own movements or others outside the tank. I find they don't necessarily immediately run and hide, however, they definitely move away from the source of the l...
