I recently had a drop in the SG. It was like that for a long time, without my knowledge. One day I mesured the SG, and found it riddiculously low, both in the F8 tank and the GSP tank. So low that you can't talk about BW anymore. After a slow rise of the SG (had to take it slowly, to make sure the filter stayed cycled), I was back to normal. And you can see the result! My F8's colors are so much brighter - they are really beautiful now, with nice and bright markings on their back. My GSP is really a wimp, and still is. But when the SG rises, she gets around a little more. At least she is not hiding all the time. She leaves her corner (under the filter - she always hides there), and takes some trips around the tank. But she still hurries back to her corner when she sees me pass by.
*note to myself: when I get new tanks, move my GSP to one of them. She needs a bigger tank*I've experienced before that my GSP gets more around when the SG is higher, so I am sure that is what makes the difference.
So this is just one more proof that F8s and GSPs belong i BW. They really have a better life then.
It's good to see the difference.
