IMO, not at all! Several things going against this union.....
First, and possibly one of the main things that would make it unsuitable, is that danios temperature requirements are on the cool side from what you should keep bettas
. Danios take about 64 to 74 degrees F, and bettas about 76 to 82. Although they might do ok for a while with a betta at the betta's low end of the temp range, it would maybe be a bit on the cool side for the betta and warm side for the danio, stressing both fish in time as neither would be at their optimum temerature (stress = lowered immune response, therefore disease & illness strike.)
Another biggie, is that they're a very active little fish and should have at least a 10 gallon tank, preferably more
. In addition to this, they should be kept in a school of at least 5 or 6 or more...... so you'd have lots of "hyper" little fish zipping around your betta all day, which might be a bit stressful for him (again, important.... stress is not a good thing at all.)
Now I'm sure there are people that have kept danios with a betta and have done ok, but just looking at the general conditions for both bettas and danios, they don't really match up well. If you really want danios, maybe get another tank for a small community tank (at least 10 gal). Or, if you really want a tankmate for a betta, there are much better options.
I've actually researched danios a bit to see if they'd be suitable to put with my goldfish.... which prefer temps about 65 to 70, so cool water. Danios would be ok, but I chose not to do this because they're on the small side and might eventually get eaten when the goldies grow, plus I didn't want their high energy level in my tank.
Anyway, just my 2 cents and good luck with your fish!
