So I'm starting up a new 5.5g AGA pico and I wanted to remove the rim, but I realized if I removed the rim it would make having a lid a lot harder. I was just wondering if all fish have tendencies to carpet surf? The main fish I'm considering would be: yellow watchmen goby, green banded goby pair, clown goby, or possibly a perc clown.
Thanks for any help you can offer.
