Stella Posted September 16, 2008 Report Share Posted September 16, 2008 apart from the fact that I am strange..... Ok so my mudfish tank has a couple of self-sustaining populations of various inverts that got in there when I was feeding live food last summer. There are tubifex (never in large numbers), copepods and cyclops. What ingrigues me is that there used to be a much higher population of cyclops. Recently that has changes and there are BILLIONS of copepods and the cyclops population has really dropped away. Now I know they do a lot of stuff with invertebrates as ways of monitoring the quality of water in streams, and the geek in me is wondering if the change in population structure is telling me something about something that is changing in there? (yes my water tests are bang on) Quote Link to comment Share on other sites More sharing options...
georgeous Posted September 16, 2008 Report Share Posted September 16, 2008 Perhaps when this started, the numbers were not right, and it has only just shown itself now. Quote Link to comment Share on other sites More sharing options...
Caryl Posted September 16, 2008 Report Share Posted September 16, 2008 Or maybe the cyclops are being eaten by the copepods who are copulating madly in their own way of saying "Thanks" Quote Link to comment Share on other sites More sharing options...
