Most eels hunt with their sense of smell. When food is added to the water, they have a tendancy to snap at whatever comes close to their jaws. I've had my snowflake eel severely wound a yellow tang (which is fine now) even though the snowflake was regularly fed with a stick.

The boxfish would be easy pickings to the feeding behaviors of moray eels with it's awkward swimming.

:eek: eel & boxfish..... :eek:

Knowing that the cowfish is not a fast swimmer, not able to act quickly. You would have to spot fee the cowfish perhaps on one corner of the tank & then may be fine.

Don't forget that boxfish that are overly harrassed release toxins into the water.

Yup, most definately! No tank (reef) or no more tankmates, if the cowfish is stressed. In the wild the cowfish has no problems do to a HUGE ocean of water but in a small tank.... Your cowfish doesn't understand & not only will it kill itself but will also wipe out the rest of the reef tank! Call this getting a Royal Flush. It's a risk.

But then again I did have a shark with my cowfish at first. :eek: But I was always worried & stressed me more then anything. Later ended up selling the shark & but still got the cowfish. :lol: :lol:

So...
 

I'm a little confused.. are you guys saying that it's fine to have a cowfish in a reef tank?

Are there any corals/inverts/anem's that you should absolutely not keep with a cowfish?

In Aquariumfish magazine there is an article on this it is the current issue. Has guppies on the front.
