Nudibranch vs. Crocea

[cosmicslop]

Anyone know if these two can co-exist?

can you be a little more specific about nudibranch

 

[cosmicslop]

its a Hypselodoris bullocki, I introduced it a couple days ago and my crocea seems to be missing a part of its mantle. Being a carnivore, it seems reasonable that the nudi is the culprit. any thoughts?

 

[mbbuna]

nudibranchs are specialized feeders and the species you named feeds on sponges so i dont think it the problem


can you post a photo of the clam (and the nudi)?
