I got my tank in my basement. Lately I have seen some pretty good size spiders down there. Any recommendations on how to get rid of them. I just tried spraying one with salt water . But I have read some spiders will tolerate saltwater. Any suggestions? Candles plants etc... if this spider takes residence near or in my dt will it get my fish like clowns fish, tang one spot fox face, starfish, leopard wrasse, red damsels.
