Glad i could impress :spin1:

 

[superkat]

glad you got those buggers out!

Question is how many are in the tank I'm not seeing

 

[superkat]

great question...RC peeps...besides manual removal...is there a way to irradicate hydroids, either naturally or chemically without damage?

 

[dreaminmel]

Just to reiterate... I've never bothered removing them from my normal reef setups as they've never bothered anything. That said, I used to have to treat all incoming live rock and live macroalgae with Panacur before adding it to the dwarf seahorse tank. Panacur is not a safe in tank treatment.

If it was me, I'd leave the tank alone.

i believe i have these in my 55g aggressive, too. Thanks for the info, Mel!

The first pic in post #40 is definitely hydroids. The others look like harmless pods to me.

 

[NirvanaFan]

Yeah, looks like hydroids. I had a small patch of them a year and a half ago on a rock. No corals were around. I took them out and burned them up with a lighter. I've never seen any since. I wouldn't do anything drastic like killing your coral.

 

[pascal32]

That is the questions, should this coral move on to another place. I don't like killing anything, at the same time it could be better for the rest of the corals.

 

[superkat]

you burned them with a lighter? did you pull wings off of flies when you were a kid?

nevermind...you burned them off the rock. wow. excuse me.

 

[NirvanaFan]

Yes, a lighter made pretty quick work of the hydroids. If you want to get them out, I would suggest pulling the frag out. Take a pair of tweezers and pull/break the hydroids off the rock one by one at their base. Take the frag and "swish" it around in a cup of water. Throw out the water and put the frag back in your tank.
