Right now I have two danios, in my 96ltr tank is that ok?, or should I have more danio's?, I only used them to mature the tank a bit faster, and as thay are the most hardiest fishes around......

I think they prefer to be in schools of around six, but if you dont like them then two's ok for now if your planning to get others instead in the future

But stocking slowly is important!

If you don't like them then of course don't get anymore. Danios display their maniac swimming techniques better in larger numbers and so need lots of swimming room. If you want more then 6 or more is a good number. they are good dither fish. When they are swimming around happily they give the other fish in your tank the feeling of safety they need to be happy.
