In 2024, I posted about some custom tanks that I was fortunate to get. Out of the ten tanks we had made, I kept three. Two of those three were set up in my fish room in March 2024. The third has been in storage until now.
The tank shown above is the third one and was re-drilled just like the previous two. You can read more about them in the links below.
I posted last month about taking down my last 75g. This third custom 45g took its place. It is now set up and running with a single Sicce Space Eko 300 filtering it. It’s not been cycled, but I’ll work on that over the next few weeks. When possible, I like to let me tanks run empty for a few weeks before cycling.
Normally, I am not a huge fan of rimless tanks, only because covering them is sometimes a challenge. Most of the species of fish I keep are jumpers and will easily find the floor if they have ready access.
Typical glass canopies are hinged and designed for rimmed tanks, which often makes finding suitable cover for rimless tanks difficult.

As described in the links above, these custom tanks are rimless but made with built in, recessed glass “ledges” to more easily accommodate various types of canopies. The tanks were specifically designed to accommodate plastic tops, since there is no center brace. Fish stores often use polycarbonate sheets to cover their tanks, which typically have finger holes drilled into them. That makes removing them quick and easy.
The photo above shows the top view of the tank with two polycarbonate sheets. The were purchased from Lowes. I had to cut about 1/3″ off of one side of each one so they would fit snugly together on top of the tank. You can also see the LED light across the top of the sheets. Since there is no hinge on the polycarbonate sheets and, in this case, the light is not attached to the tank on risers, gaining full access to the tank requires removing the light.
