An i do this? I really want to make sure its clean, as it has been outside and im adding it to a stocked community. I put them all in hot water awhile ago, but only put a couple i want in the tank. Now i want to add another. (abt 2.5 months later) its a holey type rock, and used to be with chiclids in someone elses tank. Thanks! Respond soon, stoves heating up!!
