I would.personally go with more just because you can control the temp to lower or higher. Plus it will still be good for a bigger tank in the future. By my calculations you'll need 120 watts and I always round up so that would be 150 watts. I'd get the 200 imo
since they don't have the 150.
When talking heaters a lot falls in play on where you live and how cold it gets. I can run my 180 gallon on 350 watts in the summer months but when winter hits I have to run another 300 watts. I live in Ohio and my tank is in the basement
