I recently had an Ich outbreak in my 120 reef. I purchased a fish trap from drfoster smith and made my own out of a 2 liter and managed to catch 10 out of 13 fish in the first half day. The 3 fish left would no go near the traps so I tried the method with a fish hook and managed to get my blue tang, now I have 2 fish left a small blue damsel and a small green chromis and I cannot catch them for the life of me. I have spent over 20 hours in the last 3 days. I am getting extremely frusturated. Is there any way to knock them out or make any sort of miniature speargun, I dont care if they die in the catching attempt I just need to get them out so I can rid my tank of Ich. It just so happens the last 2 fish are my least favorite and first fish I ever got. I cannot drain my tank but I am open to pretty much any other method.
