[Ahbaloch]

Not sure what this is


Not a bristle star,

I dose alegebarn tisbe pods,

And reef nutriends tigger pods

Is this something from the tisbe pack?

 

[Ahbaloch]

I have trochus snail, margarita snail, nasarius snails, asrith snails

 

[Ranjib]

hydroids i think. Is this a new tank? I have seen these things when starting a tank, they tend to go away after few weeks

Hydroids. They should disappear eventually. The last couple pics are the hydroid's medusa form (pretty much a jellyfish)

 

[Ahbaloch]

Tank is little less then 2 months old, where these are in

 

[Ahbaloch]

Are they safe?

They do sting but they shouldn't cause damage. Your snails will run into them, get a little freaked out, and move around them. If you don't like them you can always suck em out (Personally I like the weird stuff and keep a spare 10 gallon for all the hitchhikers I find)
