I previously posted about my gravid danio. There were no males in her current tank so I sat up a 2.5 gallon tank and added 2 males to try spawning. Theyve been in there since last evening and I gave them frozen brine shrimp. After dinnee tonight they have started chasing each other believe they are spawning. How do I know when there done? How soon do I take out the adults? And will she get thin riggt after?
