cichlid7 Posted April 14, 2007 Report Share Posted April 14, 2007 Just wanted to know if a pleco can live in water with a PH of 8.2 Cheers Quote Link to comment Share on other sites More sharing options...
SpidersWeb Posted April 14, 2007 Report Share Posted April 14, 2007 Common Plec and Redspot Plecs are very hardy fish and can tollerate and even thrive in adverse conditions. I wouldn't expect any problems with a high pH. Highest mine have been in has been about 7.8 but they didn't even blink at that. If you're looking at fancy plecs or bristlenose it may be different, although I do know of one family of regular bristlenose that are breeding in pH 8.2.

Faran Posted April 17, 2007 Report Share Posted April 17, 2007 Hi Cut with rain water..Phill I believe the cichlid owner was asking if the pl*co would survive in that pH, not wondering how to lower the pH. By the user name "cichlid7" one would assume that they own Malawis and/or Tanganyikan cichlids which have a stable environment at that pH in cichlid7s tank. cichlid7, SW gave some excellent advice and we're still wondering what pl*cs you were thinking of? If it's a captive bred BN I really don't see a problem, but if you're thinking of a fancy pl*c, then they are most likely wild caught and I strongly recommend not subjecting it to such high pH levels, as most 'fancies' come from the Amazon with a <7 pH. That said, the common pl*co (Hypostomus Plecostomus) is wild caught and bloody tough as nails. As long as you acclimatize them to the conditions slowly they can survive just about anything.

rcon021 Posted April 17, 2007 Report Share Posted April 17, 2007 the common pl*co (Hypostomus Plecostomus) is wild caught They are not wild caught, most are pond raised captive bred stuff. If you were going to have plecos in high Ph, then go for with Bnose or the common red spot etc. But they can come under attact fom cichlids (going by the ph you have suggested), especially the eye.

cichlid7 Posted April 17, 2007 Author Report Share Posted April 17, 2007 Hi I think it's is a common pleco I took a photo of it. Quote Link to comment Share on other sites More sharing options...
flatfish Posted April 17, 2007 Report Share Posted April 17, 2007 Looks like a common pleco to me. According to a popular online site, they can handle pH's to 8.0. However, if you're thinking of placing it in an african tank, remember that many plecs require bogwood in their diet (apparently many of the good algae wafers have that covered) and enjoy hiding in it. Red spot plecs, Pterygoplichthys gibbiceps, apparently can handle pH's to 7.8, so they might be worth a go. However they can grow to 45 cm. Some fancy plec species do come from South American rivers with remarkably high pH's. For example, flash plecs (L204) can handle pH's to 8.6 and apparently have been kept successfully in African tanks, although given their price and their fondness for bog wood (its an essential part of their diet and they love hiding in it) I dont know if I'd risk it. Probably safest to stick with the cheap species. Quote Link to comment Share on other sites More sharing options...
