Nope! If there's food they'll stay. Mine mostly transitioned to the backside/underside of rocks and the sump. They're just harder to see/find. Great, I dose phyto 3 times a week! I'll do more when I start to add sponges and larger dusters.
Still have a couple fish to move over from the cube to the peninsula, but the terror has been relocated. Doing some sump maintenance on both tanks today. Cleaned the tiny tank.
Don't worry, he knows a guy. One thing about Kev, he's not got a serious bone in his body! I think he used to, but then he broke it so... I think you are thinking of your wife Tim, poor gal. I hope she is feeling better!
