Sorry I'm not sure if I should post this here in the Freshwater Disease, Health, etc, etc section because it's not really a disease on a fish or any other living thing but just a growth on the rocks and suction cups. I've had my African cichlid tank set up for about a week and I just not noticed (I've been gone for the past 5 days) that there is a white fungusy-looking thing on my rocks and on the suction cups. I'm not sure what kind of rocks they are, but we didn't rinse them off before putting them in the tank. There are no fish in the tank yet. The "fungus" looks like a little web like, but more like a whitish bubble with weblike strands that attached to anything on a different surface within 2 or 3 inches. The "fungus" is not very transparent. My brother thinks that it might be the aquarium salt (some kind of salt sold for african cichlids; I'm not sure what kind it is) and that it expanded or something. I'll post a pic tomorrow.
