Advised by the people at Petco, I bought 6 zebra danios and put them in a filtered and heated 10g with my male deltatail, Saturn. The first day, they were zipping around everywhere and Saturn was just swimming around in a circle across the back of the tank. I thought it would just take them some time. Saturn ate just fine last night even with the danios in there. (I am netting him and holding him in the water while he eats, and he doesn't eat the danios' flake food.) I am at school right now so I don't know how they are doing. Do you think this is an okay setup? Or should I return the danios and get something more docile, such as tetras? I honestly want to keep my danios if possible, they're growing on me. Thanks.
