I agree, i have a 200 litre tank, as i think i stated earlier. The fish will grow longer than my tank!!
Done a little research and it looks like it will eat my fish, the rainbow shark is scared to death of it, so i have had to seperate them off as the rainbow keeps trying to fight it.
The LFS has said they won't take it back because they do not have the means to look after a fish that will grow that big, so they knew what they were doning when they sold it too me.
Would a proffesional tropical store take it off my hands?
