Hydroids?

[KendraB]

 

[Lionfish Lair]

Yup!

 

[KendraB]

Mother...

 

[Lionfish Lair]

Do you ever see any polyps coming out of the tubes? If not, they could be dead.

 

[KendraB]

Well at least it looks nice next to my aipstasia though right?

 

[Lionfish Lair]

That's an appy.

Edit: oops sorry, you already ID'd that.

I just spotted it so I have no clue. Colonial hydroids right?

 

[Lionfish Lair]

Yes, you are correct. The brown tubes will stay until you pull them off (and they'll be on there tightly) long after the hydroid polyps are dead.

@Lionfish Lair what eats or kills the hydroids

 

[Lionfish Lair]

People use chemicals for certain types and I'll shout out to the #reefsquad for that info. I've had many types, but I've never done anything except manually remove them. Mostly I just watch and see what they'll do.

 

[izzyishh]

i have a few that are on a rock but i have chalices and acanas glued on it and would be a pain to pull out

 

[Lionfish Lair]

What are you feeding your tank? Anything with small particulates or perhaps phyto that encourages zooplankton growth?

 

[izzyishh]

dang lol the i feed 2 brands of mysis, lps pellets, and reef roids lol i occasionally see them catch mysis buy the hermits eat them

 

[Lionfish Lair]

Heh, I think we at least we know why their numbers are going up.

Detritus can also encourage them, as it's food for their food.

 

[izzyishh]

yeah so far they dont bother a thing im having more of and issue with stupid blue clove polyps can wait to upgrade to get rid of these dang pests

Our tank is not off to a good start, thanks to doing no research & getting some awful advice from a LFS rep. We started our 32 gal biocube with 2 clowns, a cardinal, 5 snails and 5 hermits, 20 lbs of live sand and 30 lbs of live rock. We are now the proud owners of hair algae, aiptasia & colonial hydroids.

 

[KendraB]

Ok I see now that you said these may be dead. I obsessively look at my rocks to make sure nothing is growing or changing, and I've never noticed it before. It is pretty hidden, so it's possible that I've never spotted it. I'm hoping dead means they can't spread though..

Those hydroids could be chipped off I think, they don't look deep. then a dab of putty and glue. Ive won back worse rocks than yours to worse hydroids. Of late, when I can get the rock out, I use a flat screwdriver or chisel and lightly scrape the appy off the rock. The rock is soft. with gloves a carpet knife works. Normal stuff, nobody warns us about when we start.

Hair algae is pretty easy too in a tank that small. Unless its bryopsis. But Im wining that too a bit.

Of course its on a huge piece of rock on the bottom. We would have to completely dismantle our entire tank to get it out. [emoji24] If it's dead, is there any point in removing it? It's hidden so it's not an eyesore issue.

Thank y'all all for your help so far [emoji5]

And I just looked up bryopsis, and that's definitely not it. Just plain old hair algae. We took the rock it was the worst on and scrubbed it, rinsed it, and stuck it back in. We missed a couple spots, but it's much better than before.
