40 Gallon breeder options

vldka · May 30, 2026

I've been looking at adding a larger tank in my home office. The room is small and it has a lot of electronics in it, so i'm leaning towards a 40 gallon breeder tank with no sump. I was looking at the Fijicube DIY AIO for filtration/heating/refugium space. Does anyone have any other pics or setup recommendations?

What's your limiting dimension? Width, or Depth (distance from wall)?

I have owned both a 40g breeder and a 60g cube (24" ^ 3), and I found the cube to be a great size/shape tank.

If you can afford to be ~30" from the wall, you could look at 60g cubes.

Innovative Marine 40 AIO. If you like the cube look JBJ 45.

Biggest dimensional limitation is distance from wall. I’d like to keep it under 19”. There is Tideline 62g AIO that is 48x18, but I’m kind of nervous about a rimless in my home office.
