@brett_schn - the rectangle 2.5g tank? Yes, it will on the long side. Not sure if it'll fit on the shorter side. It's a great filter and gives enough flow where I feel a powerhead isn't needed which saves space inside the tank.
I ordered a fountain submersible light to put inside the filter to help grow the chaetos. I'll get the light in tomorrow or so.
