Moved these on shortly after I made the first post, trouble is they spawned, I missed 3 fry so tomorrow I am emptying the tank taking all the fish out and getting rid of them and maybe the two juvi biffa's
As everyone else said, I'd keep them if they're both the same gender, and I'd at least keep one if they're male and female. You have some beautiful cons, if you have the space for them, keep them because they're gorgeous!!!
Although if you really don't want them, I'm sure someone will.
