hehe ... will scare the hell out all my fish. I don't want they hate me whenever I come close to the tank though. It took me so long to let them feel comfortable and happy to see me. I can move my arm around the tank and none of them run away, they actually want me to pet them sometimes. I know you love your fish just like me, so you know what I mean
But I have to say, you really have a lot of brilliant ideas though. I can tell you can do a lot of things around your tank.
I have a lot of small colonies, I am going to do with them the way you told me, but outside the tank only.
