Sump Infested w Little White Critters

[RickyMcG]

Nothing in the DT of my Fluval 13.5, but the sump is totally infested with these things.

Kinda look like squishy aphids. Have what looks like a forked end. (hard to see — they're pretty small).

Seems like this just started in the past week (with intro of some new coral a week ago mb).

No idea what these are. Wondering what to do about them?

 

[Maritimer]

Do they move, or are they anchored in one spot?

If mobile, they may be ghost flatworms. If stationary, they may be pineapple sponges. Neither are a major threat - sponges are a positive benefit.

Could be isopods. Hard to tell with them out of the water. Can you get a picture in water?

 

[RickyMcG]

I'll add that one of my clowns has what appears to be a worm (long stringy, white "poop"). I just started a round of prazipro.

Thanks. Don't see any movement.

Looks like Copapods they are good for your tank probably hitchhiking on your coral

Internal parasites.

See new pic above.

[BitFix]

I would say copepods or isopods, most are beneficial, with a few rare exceptions which are parasitic

 

[Neo Jeo]

It looks like they are attached. I will say a sponge, I got s ton of sponges when I started to feed live plankton .

 

[RickyMcG]

Thanks everyone! I think I'm going to have to (somehow) get a better picture...way too many opinions here. I'll see what I can do to get more definitive.

 

[Sumo Reef]

I have these too. Tiny pineapple sponges!

Thanks everyone! Did some research on pineapple sponges, found some hi-res pics and agree. Glad to know they're not a pest.
