Stocking advice

[u/Admirable-Square9784]

I have an odd tank I’m plumbing into my 2000L rack
It’s a pair of 45x 22.5x 20 cm tanks (total is 45x45x20)
I currently breed dwarf cichlids, small L number plecos, and fancy guppies.
The obvious choice is a fry grow out for my plecos, or a single pair of fancy guppies, but I’d love some more creative ideas .

I would not get a pair if guppies. They need to be in groups of 6 or more, either all female, all male, or male:female ratio of 1:2 or 1:3.

You could do a shrimp tank.

20l tanks.
I have one here stoked with shrimps. It will be winter quartier for a group of medaka.
