PARROT FISH there i said it

Before anyone has a dig I know they are hybrids and should all be destroyed before birth etc etc ,but I have brought a second hand tank and I got 2 blood parrot fish with it .
I am not willing to get rid as I wouldn't like someone to get rid of me just because of my parents...
Right the problem I have is they are both attacking the "pleccy"(not sure of the correct name)which also came with the tank this is constant attacking all day and night when one stops the other starts apart from seperating them (I only have the 1 tank)what can I do? sensible answers please no hybrids must die nonsense thank you..:help:

sorry should have said 240 litres.
here is the tank (well the same tank I have)

As to returning the pleccy It came with the tank theres nowhere to take it back to (private classified not from a store) aparently they were living very happily together before the only other fish in the tank is a "Bristlenose"(suckermouth catfish) which has been left alone

If thats the only option then that will have to do but I would prefer to keep them all (the tank is a replacement for 1 that got smashed by burglars and the fish left to die)I was hoping they would settle down and get on but this has been going on fo 6 days now and I am getting stressed about it(well stressed for the pleccy)I have only had this set up for 10 days the first 4 days there was no problem someone suggested the pleccy would "smell" different as there had been a change of most of the water and the algy it was eating would take time to grow back when it did the pleccy would smell the same as before and all would be ok pardon the pun but to me that sounds fishy or am I wrong? by the way the pleccy is about 10 inchs long from nose to end and a dark Leopard pattern.

The pleccy is about 10 inches long in total but I live in the UK sorry.

as to hidey holes there is a large piece of driftwood also I have made some caves (of sorts) with the rocks that came with the tank and also in the corner is 1/2 a trawler about 15 inches long and about 10 inches across which is hollow but the parrots hide in there whenever I lift the lid .
