your simple household striner will work fin as long as you can get them away from decors and corner them in the glass to catch them... are you transferring them often?
have you tried this snow, I can promise you it does not work, you have several problems, including that the strainer has too much resistance in the water to catch the fish, if you did trap the fish between the glass and the strainer, how do you then get the strainer containing the fish out of the water?
also the solid hard surface of the strainer could cause damage to the side of the fish.
I did try to catch a fish with one of these once, and I will never even think about it again
