Hi I recently bought my Betta a decoration from Amazon which came back today but it’s got really rough edges on it even though the reviews said it was Betta safe, it’s clearly not! I paid pretty expensive for it, so I was wondering how to go about sanding down the rough bits to make it safe for his fins? The corners are rough and there’s little bumps on it too that are rough. If you guys want pictures let me know and I’ll insert some. And please can people link me some Betta safe realistic looking wood? Thanks!
