Some people have had luck with fishing their fish out. I stopped short of suggesting it because the one and only time I tried it, it didn't work out so well for me. Plus when you go to Fishin' Tales or whatever the store is that you get fishing hooks from and ask them for one 1/8" hook to catch a fish out of your fish tank is priceless, and then they look at you even funnier when you explain that using a net is out of the question. Here, if you want an amusing read, read about my attempt to catch a sixline here:

However, it may be worth a shot if you think you're up to trying it. Definitely use pliers or something to get the barb off the hook though so that you don't injure the fish too badly. I dunno, maybe I'm just not cut out for fishing.
