wyterabbit Posted November 29, 2022 Share Posted November 29, 2022 I recently setup a new tank that I was given and I just noticed that there seems to be some kind of white/yellowish mold on the silicone. The tank is brand new and has no fish. Just some aqua soil and some new plants. I can easily scrape it off the silicone but I am worried it may be contaminated and will harm fish when I decide to add them. Has anyone ever seen this before?
