Teddy Roosevelt was tricked into calling piranhas dangerous.I'm fairly certain that the whole 'piranhas eat people at any whim' thing is an overdone myth...but regardless, thanks! I don't think I'd go with them because they're basically illegal everywhere I look in the USA...
For a catfish, a Raphael could work, they are between 6-9 inches, but hide a lot.
Smaller rays like a teacup should fit.
