I was going to get a few of these at petsmart but someone said they are prone to ich and I need to put them in a different tank by themselves before I introduce them into my 55g with a male jd. Well I don't have any other tanks to do this. Now I am afraid to get them, what if they kill my jd (ich). Is there any catfish that can go with a male jd that isn't prone to ich.
