Currently using some barbers scissors which are perfect for cutting but because the tanks so small in comparison to my hand I can’t trim the right hand side without my left hand squashing the left side carpet and I keep uprooting my carpet, not fussed with this tank anymore as I plan to get a slightly longer tank soon and use Monte Carlo but would like to get some proper scissors so I have the right tool to cut a nice even carpet, surgical scissors is a good idea thoughI am continuously looking for better scissors. Right now I am using surgical scissors (specifically blunt mayo scissors) and they seem to be working well. For something a little smaller you can consider personal grooming scissors (typically used for nose hairs ;p. ) Or if you want something branded aquascaping you can look into spring scissors.
