You'll have to wait till your orinos are a lot bigger. I'm guessing that mono is about 13" and growing. You'll have to wait till they are closer to his size.
his colors improved when I transferred him to the my big tank
@Timthebadass
The mono is 14inches last time I checked..
My orinos are 4inches..its a long ways to go for them to rich the size of the mono.. how long do you think that would be if let's say they are given the best conditions for growth?
