Hi, i have started to become really concerned about my bettas fins i have noticed a few times my cories chewing on him. I'm wondering if he could be stressed or are the cories causing damage? He's in a 16gallon 0 ammonia 0 nitrite 5 nitrate. I have also noticed him chasing the cories but no nipping. Any help would be appreciated. I have added two pics one taken a while ago and one today. Thanks
The light in the second one doesn't show his color well but it's the same as the first pic just different tanks.
