I have a large community tank with a Dat, a CK and some other fish. Right now the Dat is about 2" and the CK is about 5". Assuming they are both healthy and well fed, will the CK grow so much more quickly that he will be trying to eat the Dat before long? Will their growth rates be close enough so that the Dat always stays too big to swallow? I've never had a Dat, but I know they are slow growers. Just trying to plan for the future. Any help would be appreciated.
