anybody fan of non posionous sea slug

i have two sea slug very hardy slugs been alive for a while but don't know what they eat so far i found the names of them phyllidia varicosa, phyllidiella zeylanica. any info on the two would be helpful.

 

I believe that phyllidiella zeylanica, and phyllidia varicosa are sponge eaters.Also usually phyllidiella types can expel poisons

 

i think i just read that about one of them the other i have wrong id on of course lfs said that none were poisonous thats why i purchased them. thanks for info.

 

lfs traded it back for some astrea snails. yeahhhhhhhhhhh
didn't believe it was poisonous so printed out info on some of the stuff they sell that is poisonous since apparently there are not to well educated on it.

 

good trade
