I have a group of zebra/long tailed danios in my ten gallon tank. The zebra danio, which I think is a female b/c she looks VERY pregnant, constantly chases ALL the other fish in the aquarium, especially my little male guppy. She looks like she is gonna pop any day now and I have a net breeder but my female guppy is in it b/c she is pregnant also. Is this chasing a sign that the female wants/needs or own space or something? Should I get another net breeder and put her in it? Any advice would help! Thanks!
