Review on 🐟 Medium-Sized Penn-Plax RR1007 Mushroom Rock Aquarium Ornament - Dimensions: 5.5" x 4" x 7.5 by Julia Lewis

I bought this and soaked it for 24 hours before putting it in my tank. It smelled a little odd for the first week, so I scrubbed it off during my weekly tank cleaning. When I took it out of the aquarium to be cleaned the following week, it smelled like burnt chemicals! no cleaning will get rid of the smell. My fish has discolored gills (paler than usual). After a big water change and trimming removal, he seems a lot happier. I would not recommend this decoration even though it is very cute.
