Can someone ID these.

They reproduce sexually, female carries a brood pouch. 2-3 months with no food and they should starve themselves out.

Since there’s a bunch of them in different sizes does that mean they have a short life cycle or somehow they all came together?

Can’t figure out where so many could have come from. I dip all the corals and put inverts in one by one by hand. Wouldn’t that mean the female with the pouch should have died in the dip ?

Dips aren't 100% effective... It's possible they've been in there for a while and are just now big enough that you're noticing them. If you're catching many different sizes I'd suspect you have a healthy breeding population.

In 3 weeks? Lol that’s scary

If they eat meaty foods you could probably make a trap to catch them. May not be 100% effective at eradicating but might help.

So when I did the curl up test I took one out of the water and it didn’t. But I was poking them this morning in my holding jar and they ran first but a few more nudges and they rolled into a ball. Does the Aegis have the ability to roll into a ball too?

The one that rolled into a ball isn't predatory. I'd acclimate a Molly to the tank to see if they go after it for piece of mind.

It’s been fishless system to prevent ich/velvet from getting to display. I might try and setup a temp rank and try that.

I found their home. The sponge filter in HOB unit is full of them. I’m going to replace it with new and continue catching them. Also working making a trap.

Joys of Reef keeping lol

So I got a white molly acclimated and put it in a 2gal acclimate box with 20 of the isopods of difference sizes. Been in there for 18 hours and they are more interested in the corner and false bottom than the Molly. If they attach to they stay on? Or I have to catch them in the act. How long would you say I should leave Molly in with them to have my mind rest at ease.

I’d like to take the Molly back to the store when done. Hopefully sooner rather than later.

Thanks again!!

Looks like anthropods to me

That many would likely kill the Molly in short order if they were Aegids. At the least you would see some damage if only a few were hungry; I think you're good to go.

ETA--- sorry for any undue stress by the improper ID.

Thank you. Would you still try to remove them or are they bio diversity and should be left to be?

Sorry trying to google images and I’m seeing much bigger critters in that family. Is there an image library of anthropods I can find.

Just saw the previous isopod remark....I agree...sorry

Bob Loblaw · Aug 11, 2018

Anthropoda is the phylum... Every pod is an Anthropod.

I probably wouldn't intentionally add them but they'd likely end up wrasse food if they got into the DT.

Really appreciate your help. I can sleep easy. Any shrimp/crab Safe wrasse that will keep their population in check?

Bob Loblaw · Aug 12, 2018

The Leopards and perhaps a 6 Line would be the best bet of the reef safe wrasse. They still pose a threat to small crabs and shrimp though.

So I went to bag the Molly and take it back this morning and it was dead. I did see 2 of the isopods on it they were walking around on it and not attached. Is this them being scavengers after the fact or you think they could have killed the fish this quickly?

I mean it is a Molly that came from a pet store and acclimated to saltwater so I don’t known what to make of it and what should my next step be. First 24 hours no sign of stress or attack.
