Hi guys, I hope I'm not going to ask a stupid question.. but does anyone know if Terracotta plant pots are generally speaking aqaurium safe?

Can they change the water chemistry or are they inert? I'm talking more about plain, glazed garden-centre type of thing. I'm considering putting some small ones in my tank. All help appreciated!

They're inert... There are several members around here that have them in their tanks.

Thanks for that, yes I thought they were quite widely used.

I did do a little search for previous postings and I'm sure I read that someone had one that dissolved in the tank, but I didn't think that could happen once the pot was fired and glazed as surely this seals it.

Any other experinces of using Terracotta plant pots would be welcome.

I have a terra cotta pot in my tank on its side. The goldies love to swim in and out of it. Beside it I have the little plate that would sit under the pot and catch water if it had a plant in it. I use that for their feeding dish.
