does anybody have a list of bad sponges. i have several types of sponges in my tank and am wanting to find out if they need to get the boot or not. the one that hase me most worried is yellowish and hase little hair like things comming off of it.
 
i checked on melevs but it wasnt there i will take a picture tomorrow. is there a general rule on bad sponges vs. good sponges
