Sluggish things?

Last night i noticed i had two slug / snail things that had no shells. What are they? I can put pictures up if needed but they look like lil blobs / snails with no shells. There are now three of them and they are just on the glass hopefully cleaning. Good or bad if u know what they are. Thanks!

 

pic is worth 1000 words

 

Sounds like a stomatella snail. They have a small shell that's hard to notice unless you look close.
Do a google on them and see if that's what you got. If so, they are a good part of your clean up crew.

Kinda looks like him but there a little smaller so can 100% tell.

Now the question is, how did they get there? I havent added anything new for about 2 weeks

 

They can hitchhike on rock or frag plugs and stay hidden for a long time. Could have been from your last addition or a long time ago. Yours are probally juveniles.

Check your tanks a couple of hours after the lights go out and I bet you have a bunch more than you realize.

Alright thank you guys for all the help. so they are good and not bad?

 

yup quite good

 

They're an awesome way to control film algae.

You likely haven't noticed them because they are excellent at the art of camouflage. They can take on different colors, and blend into the LR with the multitude of colors that seem to stick to their shell (teeny tiny- but it is there) and body. They also breed like rabbits- so it's a difficult population to kill off, even if you have something in your tank feeding on them.

 

Yeah, definitely a good thing to have in your tank Porky. Have fun brotha.
