When my parents gave me my 55 gal 2 weeks ago, we had to obviously net the fish and bag them for the trip. well....when we netted the upside down catfish, his side fin grabbed the net and ripped it. We had to cut the net just to get him out. well, a part of the net was wrapped around his fin. I thought maybe he would be able to rub against something and get it off after we tried in vain to do so. Unfortunately it is still there. First off, I have the problem of catching him without the net b/c I dont want him to get stuck again. I was also told he has "barbs" on his fins that hurt if you get stuck by them. Any suggestions on how to get this tangled net off of his fin?
