A large elongotus is something to be scared of! They are EXTREMELY aggressive! Some large piranhas are so aggressive I wouldn't doubt they can take on a shoal! Well they would try and get a lot of kills I wouldn't doubt a full grown elongotus can take on maybe about 4 rbp's but I wouldn't give it more than that as more than 4 is a high risk. But alone they are top dog!
