Hitchhiking oysters growth and progress!

[AydenLincoln]

I like to look at my tank at night sometimes and pray I don’t see any bristleworms lol! I have yet to see them and I have looked very hard so I think I can confidently say I am bristleworm free from careful dipping and inspection! Woohoo! I did however discover a fairly small to medium sized gray brittle star I have never seen before and what I thought was a sponge for the longest time is actually another oyster. And upon further inspection it’s definitely an oyster or another bivalve perhaps growing under the sponge but it moved/shut and sponges don’t do that lol! Just for comparison this is what about a year of growth looks like on both the oysters. I’m aware they may be clams too but I think they look more like baby oysters to me.

I see sponge and the typical eyelash shape fan of a barnacle.

FWIW if your tank is devoid of bristleworms, your tank is very unhealthy.

It’s not sponge or it’s a sponge growing on an oyster is what I’m saying. The one thing you see is a tube worm/feather duster or a hydroid but not a barnacle. Not all tanks are going to have them. I have lots of other critters and worms just no bristleworms lol. Also my fowlr tanks will never have any.

Cool! 4th picture with the one open is my favorite.
I've never seen any type of bivalve in my tank but agree that yours look oyster-ish to me.

I agree that a good tank should have a couple, but most of the time people have a lot of bristleworms because they feed too much.
