I have a 75 gal with a 20 gal sump thats cycled but has nothing in it yet! I have realy been wanting to et a group of Demasoni with a raphel cat for some time i was wonder how many and or any other tanke mates i could add. I was wondering if johanni M.'s on male and 3 females or severalyellow labs would be ok? I also have a 29 gal, that i want to put some kind of cichlids in as a planted cichlid tank what are some suggestions? If i dont do cichlids in the 29 i was wonderg how hard a salt water 29 would be?
