Can I use seashells I found in the ocean in my freshwater tank? I found two huge ones and ones got a hole on top but I thought they would make a very nice little hang out for my dwarf gourami.

I have put some 10 to 15 seashells in my 10 gallon tank. My guppies and platies like them. I cleaned them before putting them in my tank. I kept them 2 days in water and changed water after every 3 to 4 hrs. removed all salts and sand. They really look nice in my tank.

They should be safe. But I would rinse them very well to get rid of any salt like they mentioned above

Also be aware that it may affect the pH of the water, depending on hard your water is to begin with.

They may not only effect PH slightly, but they will also slowly raise GH over time as they dissolve. As long as the tanks not loaded with shells though you shouldnt see a huge difference, and with regular water changes I don't foresee any problems. If you have inverts like shrimp or snails, it will actually benefit them having some calcium being leeched into the water as they need it for their shells.

Yes I'll have to keep an eye on my PH I do have crushed coral in my filter because my PH had dropped significantly and suddenly to a 6.6 and the corals have kept it to a consistent 7.2. If I see it rise too high then ill just take the coral out. Its one giant I guess conch shell. The fish seem to love it. they hang out in there constantly now and it looks very nice in there.

That's the shell. pic came out sideways lol. anyhow it has a hole in it but the fish love to swim through it and some get way in there and hang out. Cute to watch how much they love it. I think that's a conch sell but not sure.

Oooh, excellent news, I had read somewhere that you couldn't keep shells in an aquarium at all!

I have another same size without a hole in it but I figured the fish would like the hole to swim through and they do. Ill let yall know if I notice any PH spikes so that way we'll know. so far so good though. Ill be the guinea pig lol
