I got a couple new females yesterday for my 30 gallon sorority (up to 7 girls now) I acclimated them and then headed out for awhile. I come look in the tank and see this... (I only snapped a couple quick pics before separating them, dont worry)
Ember (blue) and Chloe (green) are not fans of eachother. I removed each of them and left the other to see who was the agressor, it was Ember. So she's in a 1/2 galllon tank right now until i figure out what to do with her.
So just a quick reminder to keep an eye on females when putting them together!!
