Hi guys, I recently bought a pair of apistogramma baenschi inka apistogramma and when i viewed them at the display tank of the shop they were peaceful and getting along but the next day when they were in my tank the male started being aggressive towards the female like chasing and mild nipping of fins and was wondering what could be the cause of it happening is it because of the female desire to spawn? which can be seen that the female was doing tail wagging and turned yellow. The pair are relatively young abut 3cm in length and I would appreciate any tips in helping to assure me that it is a normal behavior or if not suggest any tips in helping to solve this aggression
