One time I was just chillen in my apartment when I heard a big splash and then some flopping around. My poor ornate wrasse was behind the tank gasping for breath and covered with dog hair. He made it really tough to get him out because he flopped diretly to the middle of the back of the tank, and I had to really strech to grab him. I just put him right back in the tank, looking back, I probably should have rinsed him off first because he was covered in dog hair, he looked like a rare long haired wrasse!
I am so glad I was there to see it. I have that tank covered with a sheet of eggcrate, but I had a hole cut out in the middle that I sat the PC light fixture over, that way if I needed to put my hand in the tank I can just slide the light out of the way. Well it turns out I had not replaced the light properly last time I was working on the tank, and there was a wrasse size hole for him to jump out.
