alright,i didnt know that they got that big,i knew that they are highly agressive because i used to catch babies(6 to 15 inches)and i would walk about up to my knees and let them go,they used to turn around and try to bite,but i still like them.oh well,i guess ill just set up another fw tank,i always liked ropefish,do they have any special care?and what size tank would they need?
