Stupid 6-line

[Matt]

Our 6-line wrasse as decided to surf over the overflow, and is now hanging around in there. It is a small space (6" square, 20" water depth), with 1.5" durso and a .75" return coming up the middle. In other words, not much room for a net.

When I put the net in, he dived straight down into the furthest, tightest corner behind the plumbing! Doesn't he know I'm trying to help? I drained the overflow, but he was still in an inch of water in an inaccessible spot, and I couldn't reach him.

I don't know how I'm going to help the little guy.

Any tips?
