danio questions

IMO, neither tank will work for them - they need to be in a school of 6 preferrably, so that they are happy, and they've very active fish so they need a lot of room. Since your other tanks already have quite a few fish in them, I'd say avoid the danios.
 
I've got a lone danio that chased all of the others until they were so stressed that my tetras ate them :-( . Now the lone danio dominates the tank even though it's one half to one third the size of the other fish. :crazy:
 
yeah, a lone danio w/o others of its kind will be very antisocial.
He needs friends....more danios to play with.
He's very lonely. :(
 
My lfs sells zebra danios 2 for $1 so we usually by 12 and put them in our 125 gallon as feeders. They definitely look cool when they all swim together.
