What is this

[Mo8cinco]

It round and sticks to the glass but the other side of him looks like a pyramid

 

[Bonz]

Sounds like a type of snail

 

[Mo8cinco]

It doesn't look like a snail even though the back is a pyramid it's not a shell it's all a jello like skin

Dont take my word because I may be off but, nudibranch? I don't think so because they are a lot more colorful but they are only skin

 

[Mo8cinco]

Googled it and it doesn't really seem like that those things are REALLY colorful mine is only black and white. Could it be a slug??

 

[hackteck]

google chiton could that be it?

 

[needmorecowbell]

Lol THAT^ is what I was thinking of but couldnt remember the name.

 

[Mo8cinco]

Na not one of this nether to be more specific the too is like a volcano where it's round and comes to a point and has a hole at the point, and the bottom is a suction cup

 

[Krypt]

May be some type of limpet.

 

[Flake]

I'd have to agree with limpet.

May also be an abalone, we had a few that looked kind of like that.

 

[Mo8cinco]

My friends it is indeed a limpet!! Thankyou very much for your help as always rhanks to you and this application I have more saltwater Aquarians knowledge

 

[Gregcoyote]

Yep..it's a very nice limpet. Don't like them on the boat hull, but okay on the old aquarium wall.

It is a nudibranch mine is all black and had a white stripe on its back. The black is just a skirt that covers the shell of it. The white you see is the actual hard shell under the black skirt of it. they don't harm your tank, mine has been in my tank for a while and always leaves my coral alone.
