Help id critter

Hello everyone I have an issue that hope someone can help me with. Today there is a creature in my tank that can’t take a photo of because it keeps to the shadows beneath the rocks on the sand. It’s white about the size of a quarter and it seemed to move and thought I saw it breathe. It’s shape is somewhat flat. I know that is not a lot to go on. The tank is a twenty gallon that has been up for almost three weeks and was seeded with turb start and has three fish,three snails and three crabs. Thanks for your help.

Do you have liverock? It's most likely some type of worm. Like bristle,bobbit,spaghetti Medusa etc. Out of all those the only bad one is a Bobbitt and I doubt you would see it in a 3week old tank.

Is the object stationary? Does it sit in one spot? Because breathing to me sounds like a tunicate or sea squirt.

Yes I have live rock from my lfs one piece was from Florida. thanks for the quick reply should I try to get it out of my tank

 

[trainbob]

Either there’s two in the tank or it moved.

If you can rotate the rock for a picture, that would help a lot. If it's a tunicate, keep it, it may also need light to survive.

 

[Goaway]

Tunicate will remain attached to rock

 

[trainbob]

It is on the sand bed not on the rock but I did a search for seasquirt and a white blob came up that looks like the one in my tank. Will try to take a photo

 

[Goaway]

It's not dangerous at all. Most of them die off after awhile.

Try using a flashlight to light it up for the pic. It actually works well. Goodluck!

Well problem solved thanks to Mibu moved the rock around to try to take a photo and with the rock moved realized that something was decomposing in the tank.siphoned it out and replaced the rocks. It looked like it was breathing but was just swaying in the current

 

[Goaway]

Glad you got it fixed. Best of fortunes on the aquarium!
