Puffer and a Loin?

[i have crabs]

i had a saddled toby a snowflake and a lion together with no problems but the loin was a lot larger than the toby,the toby lives with a couple cardinals and has never picked at any fins,while a had a fingerprint toby that picked at everyones fins so it might just depend on the fishs personality wether you would have any issues or not.
