My senegal bichir was being a real pain in the ass to my knives, so I moved him to my other 55 for a while, so they can gain some size. I honestly thought that it was a strong enough swimmer to not get suck into the AC 110 filter. I though wrong. Two lesson learn today: If it can fit into the filter inlet, it will get suck into it, and Bichirs aren't that strong of swimmers.
