No, I would not breed with it, I would give it a small tank with a few shrimps and a cave 🙂
You mention space being a problem also, so that might solve it a little bit 🙂
But the blue line sp species you have, I would be rather proud of having it, –
At the moment no one has mentioned having it in our last Census, (and we should really have it there I think) and although theres yet no prober species description and the name is not ‘proper’ and so forth as Peter describes, – in my opinion its a really interesting area to investigate.
A lot of the fish in the aquaristic shops are indeed sp. something anyway. At least yours could be a continuation of the same sp.species 🙂 ..
Well, I understand your feelings too, just being positive .. and they are fantastic fish.
