so i have two FX5s on my 220g along w/ two emperor 400s. i alternate the cleaning of the FX5s so the one i cleaned today hasn't been opened up in a little over 2 months. so after shutting it off and unhooking it i carried it to the mop sink to drain it through one of the top ports before fully removing the lid. so just as i tip it and get water flowing out pops a jumping and wiggling Angelicus Loach. it has been missing for just about 2 months as well. i just cant believe he survived all this time on the top basket of the filter. just thought i'd share.
