Limpet snail and lyelllw

[Sir Chris]

So I’ve had limpets for 5 years now with no issues other then them being a pain with there dead shells on the sand bed, or blocking prime real estate on the glass, or worry about them stopping my pumps. They’ve never been on my SPS on fletch. Just the plugs or anywhere there’s coroline basically.
Ive got a 100g going for 2 years now and they made there way in on some euphilia most likely on there stems since I used all new plugs and dry rock to prevent them getting in..

I did a lot of research before committing to a Yellow Corris wrasse but seems to just wait for food vs actively searching for food. I have a spaghetti worm issue my nano he’s QT’d in but hasn’t touched anything besides the food I feed. I’ve waited days to feed him in hopes of a reduced # or just a few missing but hasn’t chosen any.. he’s gorgeous but not serving his wrasse purpose.
He’s still not introduced and originally wanted a melanurus wrasse but love a CUC but have access to dwarf cerith snails of many proportions but don’t want the nasarrius or larger Mexican Cerriths to take a hit. I doubt it would go for the Black foot trochus.
Thank you

Typically with limpets and spaghetti worms the amount of food available for them to eat will determine the numbers in your tank. Personal I think they are a good part of biodiversity. I've never seen a yellow coris eat spaghetti worms.
