Sixline in overflow!!!!!

[Delphinus]

One of my fairy wrasses frequently ends up in my overflow. I think she kinda likes it in there. What I do is, I have a valve on the overflow pipe. So I close the valve. Let the tank flood up so that the overflow has the same water level in the overflow as in the tank. Shut off my sump return. Usually she swims out on her own within a minute or so and I can get the system going again. If it takes longer or if I get impatient, I might try to coax her out with some flake. Failing that, usually I just need to show her the net, she knows what that is and hates it, so usually one look at the net is enough and she swims out. I haven't had to net her ... yet. But like I said, usually within a minute of flooding my overflow she's out on her own anyhow.
