Looks like I am nearing the end of my fishless cycle (Ammonia and Nitrite dropping to 0ppm within 24 hours, and today's nitrate reading was 80ppm).

I live in London, so have hard, alkaline water. I have been reading up on fish suitable for these conditions and have come up with the following:

Assorted guppies
Black molly
Giant sailfin molly
Golden barb
Pearl Gourami

DD has her heart set on neon tetras and penguin tetras. What I have read indicates that although these are often kept in my water conditions, they may not do that well, and may have shortened lifespan. If this is the case, I don't want to have them.

Is there anything else I could consider? I am aiming for peaceful unfussy fish, as this is my first tank smile.

My tank size is 200 litres, which seems to indicate a total adult fish length of 100cm. I am confused about how many of each fish I should/can have - although I understand that the guppies are shoaling. But then, how big is a shoal???

Be really grateful for some advice on whether I am on the right track or not!
