Sorry, wasn't clear. The Amanos climb up the side of the filter between the edge and glass, then get up top and try to get out over the lip. It's not the filter, it's the access it gives them to potentially escape. Combined with the fat heater cable on the Finnex titanium I swapped in, they've been able to fit through the gap between the top and the tank lip.
I picked up some acrylic from HD. Going to try to cut a sheet so that I can provide a notch for the heater cable. Will replace the glass top.
Need to take some more shots of the tank as stuff are growing in. I'll try to do that soon. I've gotten a bit of algae back as I've noticed my nitrates coming back up. Doing some small water changes to try to reduce that.
