well, i always wanted one of these badboys and my lfs has a nice size one thats like 3" around and over 14", i never got it because i didnt have anywhere to house it and didnt wanna stuff it in my 150. but now that i got a bigger tank im wondering if its compatable with my current mates: silver aros, spotted gars, shortnose gar, rtgg. will they get along? wil they end up killing off the Lung fish? will the lungfish attack my aros n what not? i know there slow moving fish which is why i dont want it getting picked on. but the tank is big enough for fish to not have to bump into eachother anymore so i figure they'll act differently then being cramped. less agressive since theres more space? or will hunger lead them to wanting to kill it? thanks guys
