baby peacock bass

Same fish displaying different colors I'm thinking mono but I'm not 100% what do you guys think

Looking for Azul Peacock Bass either 3-5 inch or 8-14 inch, if you have a size not listed still let me know, may be able to work something out. I'm from the North-West of the UK, in Preston/ Blackpool (PR3) I can often collect, as prefer not to ship bass due to friends having dead on arrivals...

Guys I am new to peacock bass keeping and got the new juvenile about 2 weeks ago He is corentaly on dried shrimp diet and normal cichlid pellets Any suggestion on how to take proper care!
