Angus Posted February 28, 2012 Report Share Posted February 28, 2012 Hi all i constantly read in overseas forum topics of planted tanks with shrimp used as part of the clean up crews, Amano shrimps etc etc. I've never seen any tropical shrimp for sale in the lfs here. A thought occurred, how about our single native species of freshwater shrimp? I read that they can be acclimatised to higher temps. Has anybody attempted this with any success in a planted tank scenario? Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 28, 2012 Report Share Posted February 28, 2012 A few have. Do a search. They do not tolerate high temperatures. Quote Link to comment Share on other sites More sharing options...
Angus Posted February 28, 2012 Author Report Share Posted February 28, 2012 I read they prefer 20 degrees water, but can be acclimatised. Not keen on low oxygen, or ph swings, but a stable well oxygenated planted tank shouldn't pose a problem i'd hope. Quote Link to comment Share on other sites More sharing options...
blueether Posted February 29, 2012 Report Share Posted February 29, 2012 I believe that they die at about 26.5 or 27 deg Quote Link to comment Share on other sites More sharing options...
Squirt Posted February 29, 2012 Report Share Posted February 29, 2012 They prefer cool water of streams which is about 8C here. You asking too much to get them above 25C because theyve spent thousands of years adapting to the NZ climate. Quote Link to comment Share on other sites More sharing options...
Angus Posted February 29, 2012 Author Report Share Posted February 29, 2012 Not convinced about that argument. Proof being a mate's native tank which regularly gets in to the high twenties during summer, with no ill effects to the inhabitants. Granted, it's not sustained high temps like a tropical tank. But critters have the ability to cope with change in environments, otherwise a single high temp. summer with severe drought would kill off all inhabitants in a localised habitat. And as a reference noted, "When acclimated to warmer temperatures native freshwater shrimps, as do most species, exhibit higher preferred and lethal temperatures than previously. These are due to slow, finite, but reversible adaptive changes in body chemistry and physiology." Anybody with a personal experience?

SamH Posted February 29, 2012 Report Share Posted February 29, 2012 I kept about 20 of them (including a berried female) in a cold water barebottom pot planted tank. Just sitting at room temperature and a small filter to give a nice current. Why not do a cold water planted tank? Most of the plants don't mind, although they grow slower, and shrimp are wicked.

Mirio Posted February 29, 2012 Report Share Posted February 29, 2012 I think you will find most freshwater shrimps, even tropical benefit from cooler temperatures, if they're the focus. 25c is the highest I've seen Native shrimp at, dunno how high they go. But with a drawn out acclimation might be able too push them further, just have the planted tank as cool as possible I guess. Quote Link to comment Share on other sites More sharing options...

Awesome! Were they a good clean up crew for your tank? Quote Link to comment Share on other sites More sharing options...

One way is to try i suppose, which i'll have a go at, depending on the legality of collecting shrimp from the local rivers? Was hoping for some personal experiences before potentially harming any locals... Quote Link to comment Share on other sites More sharing options...
alanmin4304 Posted February 29, 2012 Report Share Posted February 29, 2012 There is a sticky by Aquila in the native fish section and it has some links which may be helpful. Quote Link to comment Share on other sites More sharing options...
Angus Posted February 29, 2012 Author Report Share Posted February 29, 2012 Cool - ta! If I end up trying this with any success i'll update the topic. Then again, do we want planted tank freaks all running off to the streams carrying nets? Any other personal experiences still welcome!

SamH Posted March 1, 2012 Report Share Posted March 1, 2012 Awesome! Were they a good clean up crew for your tank? Had mad amounts of brown algae before the shrimp, none after they were introduced. Quote Link to comment Share on other sites More sharing options...
Adrienne Posted March 1, 2012 Report Share Posted March 1, 2012 If you use the search function on the top right hand side of this page you might be able to find other accounts of people keeping shrimp. Hope this helps. Quote Link to comment Share on other sites More sharing options...
Sophia Posted March 1, 2012 Report Share Posted March 1, 2012 I've kept shrimp on an off for a couple of years (not the same shrimp) and most details are in my loach thread (see signature). As the other said there is much more if you search as we have discussed those funny little critters a lot. I am convinced my latest shrimp is dead, I had a thorough beady eyed look for it yesterday and today, still can't see him Quote Link to comment Share on other sites More sharing options...
