non toxic box fish

[sinaloa213]

i am cycling a 20 gal and i wanted to plan on getting a box fish and i know that thay can expell a toxin that kills averything i wanted to know wich box fish doesnt expell a toxin or one that expells it the least

Maybe the Blueline Cowfish. They dont seem to get stressed as easy as other but I think all have the same toxins....still a 20gl is going to be too small for any Box/Cow IMO....

thats my thought a cow/ box fish would out grow your tank quick. but i think they all have toxin in them but unless really stressed they want release them. i know everybody says oo their wipe out your tank because they release toxic but ive never heard of it ever happening and ive keep them at my lfs i work at and everything went fine. most fish seem to know to stay away form these fish.
