I've recently moved my fish from a tank to one thats double the size. I tried to keep most of the old water but that only just filled half of it.

They seem to not be enjoying it or swimming around. They just rest in a group along the floor - hovering. There top fin has 'fallen' down towards their body meaning that they are unhappy - but why?

Is it New Tank Syndrome?

My water quality is pretty much fine. Ammonia was at 0.25ppm but now it's down to 0. Nitrates around 10ppm. Nitrites were 0.2ppm, now 0. PH is 7.2. Temperature is consistent.

What should I do?
