i have two gold barbs that i recently got from my local fish store and they have adapted well in the tank and i like to call them twins because they just swim around together, anyways that’s besides the point. i was just watching my fish and noticed that one of the barbs was rubbing against the other, i’m assuming it was a male barb rubbing against the female, is this normal mating behavior? should i do any preparations for little babies? i’ve never had two fish mate before so i’m pretty new at this. I would post pictures but they just stopped doing it, both fish are pretty small as i’ve seen ones with big bellies, could mine still have a possibility of getting pregnant? thanks for the help
