Koralia Nano scaring fish?
I have a BioCube 14g with a clownfish, yellowtail damsel, tailspot blenny, and various inverts. I just added a koralia nano 240 for more flow and it seems to be scaring the fish. I have it positioned in the back right corner right below the top intake of the BioCube and it is aimed slightly left, so it adds flow to the right and middle of the tank.
The fish are now hanging out mostly in the back corners and avoiding the middle and front of the tank. Is this normal? Will they get used to the added flow and start to swim there again, or will they avoid the areas all together now?
