No offense, but regardless of the animal their health should be of importance. If it is not, why bother "caring" for it then? Depending on what type of canister you have, you may need to upgrade because as mentioned, they are rather messy animals. I would have filter floss along with carbon in your canister and rinse out the filter floss weekly, carbon replacement bi-weekly or monthly. You could always add an hob, but a secondary small canister wouldn't be so bad for just chemical media and using the larger for mechanical media....many options really.
