Can I use carbon for eel's, lionfish?

[HAAAAAAAA]

The more i read, the more I understand the danger's of chemical's and it's effects in fish like eel's and lionfish, so, just to be on the safer side, I've only seen positive aspect's when I used carbon with them especially with the knowledge of eel's slime coat being toxic and in a closed ecosystem such as an aquarium, the toxin's could build up stressing the eel (I believe this to be true) but, i still want to ask, should I use carbon?

It definitely has its pros and cons and also the confirmed aspect of it causing hlle in fish (head lateral line erosion) do I have to keep using it with its risk's? Or is there a better alternative?

The key to using carbon with minimal risk for HLLE is to use the highest grade Granulated Activated Charcoal. This article provides excellent information.

Head and Lateral Line Erosion (HLLE)

This article discusses studies performed regarding head and lateral line erosion in captive fishes. Specifically, carbon use and nutrition as they relate to this syndrome.
