I agree with Brook on space.
A 20 long would be great!
I am not really sure about moving the male?
I think I will pull fry from the pair or move the pair and leave fry in 20t..
The 55 I don't know at all what to expect?
These guys are supposed to get pretty big so I kind of figure with the breeding that happens as an extra I am really trying to grow them larger for serious spawning later.
This way I can slowly work through the learning curve as they work through the breeding curve or whatever I screw up!
I at least know now the sneaker male is out of the 55 and there are eggs in both tanks , so the learning about breeding begins now!
They do seem happy!
Just got in so need to check on fish rooms...
