I think its a beautiful tank, compliments to that.
It is a really big tank for parosphromenus, – and the disadvantage of that is that although breeding may take place, it will be really difficult to manage. Feeding the fry for one will be very difficult, you will not at all be able to target any paro fry with food. And food you will add will be so small that the fry wont really have a chance to find it.
Secondly, although I believe that paros actually thrive well in bigger tanks and also thrive in small flocks, – they will dissappear in this size tank.
As you may have found here on these pages, – we most often advice people that the idea of having paros is not for the purpose of display. Being so rare and threathened in nature we have an obligation to attempt to breed them, and for this its too big really.
Once you have many, – which also happens, – as I have for example with linkei at the moment, having perhaps 100, and with difficulties in finding other people who need them, – it makes perhaps some sense to also have paros in a ‘display’ tank. But I would then always keep at least 3 pairs seperated for breeding, so that I will never be in the situation where I suddenly have no fish left, – even if a disaster happens in the big tank.
My biggest tank for paros would be 60 liter.
