Not exaclty....we do take slatwater coral, giant clam shell etc...to use them in tropical fish tank here, large and small. The things you have to do is : * Soak the stuff with waste fresh Pineapple skin (Sarawak pineapple is the best..most 'acidic')in fresh water for a week. * Drain and put them in boiling water for at least a good five minutes. * Take them out and leave in the hot sun for two days. * Put them in your "to be aquarium" for two days and put one live tropica fish for "Live" sampling. If that fish lives, its done, if not...repeat from step 2. They do sell the processed stuff here but its expensive. Also note that many plastic and cast ceramic product does contribute to bacterias that harm fish after prolong years of use. Soory for the OT.
