Bit of a pointless argument really. If on the basis if your research you think they'd be fine in the tank, put them in. No one here can stop you and no one here has the final word on it. It doesn't sound like it will be permanent.
Not that you SHOULD put them in, in my opinion I'd put them outside and let them take their chances.
