ok so i just added 7 glofish to my 29 gallon planted tank that just finished cycling. there were already 2 normal zebra danios in there, i believe both female. right when i put all the glofish in it looked like they were fighting and ganging up on the 2 normals. then i realized there were eggs flyin out everywhere and they were just havin a crazy fish orgy. is it normal for these guys to start spawning literally seconds after being introduced. i mean literally, under a minute. i'm not really worried about it, just surprised, unless i should be worried for some strange reason.
