No problemo. It's what we do here.

For a filter, the Fluval U underwater filter series has done me magic for my big chubby eating machine of a bullfrog. I use a Fluval U2 Underwater filter, and her water has not gotten even the slightest bit cloudy ever since I put that filter in her tank. But it's your choice. A canister filter would work too, but they're very expensive.

You can buy fake water lilies that float really well and look pretty at the Mr Pets. I use them for both my Green frog and Bullfrog's tanks.

With a nice water area like that, eggs and tadpoles aren't a dream, but a possibility.

Honestly, I'd go with the aquarium silicone. Although it will cost a bit, it's better than risking it and having your hoppers get hurt.

Eggs? Hmm... I'd buy a 5 gallon or 10 gallon tank, place a underwater sand substrate on the bottom with some plants, fill the tank with dechlorinated water, place the eggs in, and wait. If the tadpoles do hatch, you can feed them frozen, then boiled lettuce crushed into tiny pieces, as well as bloodworms and "Frog pellets". Make sure to thaw the bloodworms before feeding them to the tadpoles.
