So we finally caught our goby to put in QT but I've had a burning question about him since I bought him. What kind of goby is he? Our LFS didn't know when they sold him to us. Also we have some strange snails if they can be ID'd. The goby is almost a forest green black. He occasionally has red spots and when he was put in QT he developed a long white stripe from head to tail. The snail is in a white and black shell. He appears to be red from the glass but has a sandpaper appearance everywhere else.

That is exactly it! Thank you. Are those good for anything specific or do they need anything specific to eat?

They eat bivalves.... I've heard they will even eat each other. They're not a nice snail to have unless you are particularly interested in the carnivorus snail.

Well, I think they ate one of our common sea snails but besides that they're okay. Very active. That's for sure. Thank you for the ID & info.
 
We're doing a major water change at this exact moment so don't mind the water but the snails decided to surface at this moment. Got some better pictures of the bodies.

Great shots. That's definitely a Fasciolaria.
Thank you. I'm just glad you helped to ID them. They were only $8 a piece but my LFS at the time was really bad about not knowing what exactly they had. In most cases I've known what I'm buying but not with these snails.
 
Sorry about the miss id. If you don't mind me asking how do you id all of the critters that you do? Do you have logs, books or just off the top of your head?

I totally missed your post. You didn't actually misID... it's a Fasciolaria, which a Banded is as well. I'm only confident enough to say it's a Fasciolaria and where the specific species doesn't make a difference, it's good enough, IMO.

I'm not a critter expert... I've been a part of forums since 1999, so it's basically a lot of practice. I have found a lot of great resources over the years that I always have close by. I also listen to the true experts like Leslie Harris for worms and Don Barclay for snails. Putting together that guide that @smh254 listed represents a lot of time reading about these critters. (Thanks, BTW, it's always nice to hear, smh) It's kind of like my real job of being a nurse... after you see the same rash a 1000 times, you have an idea of what it is and you know where to look next to get a specific ID. People tend to describe situations the same way, so you listen for common familiar words. Honestly, sometimes you have to not look at the critter itself, but the situation or environment it's in. If it's a snail near a bunch of zoas that are doing poorly... look to zoa preds. You can't be afraid to be wrong and you just have to throw your guess out there.

So an update on what I now know are tulip snails. Last night I was at work and my husband noticed the snails seemed to be fighting. This went on for about 4 hours until after I got home and we went to sleep. They were still fighting. We woke up and it seems the big one beat the little one. Our hermits were digging in the losing snail's shell. So @Lionfish Lair was completely right. Carnivores and cannibals.
