OK, if the fish start scaling walls and shooting webs from their fins...I'll get really worried.
I'm not very concerned about chemicals. We don't use any insecticides around the house or yard...kids and dog and cat and indiscriminate use of poisons don't mix. We're not clean freaks either, so there's no beach, ammonia and other noxious cleaners all over every surface. Mostly what there is some dirt (from lack frantic of scrubbing) and bugs (from lack of insecticide).
As long as a little spider once and a while won't choke the fish or make them sick, I won't have to yell at my husband about this.
