Yeah you have all the nice exotic fishes Now I remember ... hehe....
Yup. when everything is in status quo, nanos are easier to keep.
once you try to make some changes, that is where nanos are a huge challenge.
minor actions get magnified. I simply forgot about this when I added the new fishes.
one fish death easily leads to a wipe in my kind of situation.
But I guess all this is part of the learning curve.
Why do you want to downgrade? If I have the space and time, I would surely go for a larger tank
You might get bored with nano pretty fast.
