Right, so for the past two years I've been watching aquascapers on social media with lovely rimless tanks, filled as close to the top as possible, with no lids, that contain living fish.
All my tanks are rimless. When I set up my 90l rimless community tank, I was heartbroken by the number of fish who leapt out of it in the first couple of months, and heartbroken again when I had to put ugly clips and an acrylic lid on top so my ember tetras would stop leaping to their deaths. Now, I've had a pair of horrendously expensive wild-type Betta imbellis throw themselves out the 1-2mm gap at the edge of the acrylic lid!
I am gutted about the imbellis...the worst part is that I've three other rimless tanks in the early stages of setup. They were custom made. I asked for lids when I bought them, and was told "sorry, these tanks are intended to be open."
So what can I put in a rimless tank that isn't going to jump out of it?
