I just got back from a weekend away to find my two red turq's with (somewhat) cloudy fins, but otherwise O.K. I haven't had the time to test water chemistry but I will do tonight.

What has changed?

These two were dominant fish before I left, and the third, a pigeon blood, was getting picked on heaps. Now it looks like she is trying to lay eggs & chases the other two away from her corner - change of pecking order!

I think there has been some fighting going on - could this have caused stress &/or injury, and might the cloudy fins be a stress reaction?

Also, my auto fish feeder stopped working, so they were a bit hungry when I got home.

I plan to do a 30% water change tomorrow after work.
