Keeping Spanish shawl

[Mikemilly245]

Got this for 20 bucks at the lfs. Any advice on keeping him? Was told they feed on sponge but it looks like it’s hydroids and other soft corals. Are they really that difficult? I have a bunch of junk in my sump I figured he could munch

That is an awesome but tricky creature! The thing with nudibranchs is that most have very specific diets and only eat certain things. If you can feed them that thing then they will thrive, but they typically won't adapt even when they get hungry. Good luck!

So apparently the lfs was right and I’m overthinking . This is not a Spanish shawl and is in fact a Bubble gum worm sea slug or Hypselodoris apolegma. Feeding on sea sponge exclusively but only those from the euryspongia genus. I’m not sure pineapple sponge falls under this. I also have some pinkish purple growth on the rocks In the sump I figured was sponge. I’m hoping something in there can feed this guy! It seems like he’s munching on something cant tell what. Last resort I’m putting him on the decorator crab lol

Update: debating on scooping him off the high flow area but I’ll let it ride. Think there’s enough junk for him to survive or should I take him back? Things sweet af
