Hello Frederik.
Nice to see you have got some fish and that you want to breed the linkei’s.
I would like to say something to the set up though, – and I don’t mean to start out being ‘critical’ 🙂 but …. when I see the photos I can see that there are a few other species in there and although they may come from around the same kind of areas, – they are very different in their requirements.
The little hillstream loach is such a lover of moving waters, in fact as far as I remember from when I once had them, they really depend on it because of the content of oxygen in moving water.
And the paros prefer still or if anything just very very slow moving water.
Hill stream loaches and paros are really not good company :huh:
I just had to mention that, – but its very good that you are going to separate them into a breeding tank, that will be a lot better.
