Whatever crawls on your glass is likely amphipods - coppepods don't crawl...
Technically yes, they don't "crawl", they hop. But that's arguing semantics over what ultimately is a method of locomotion over a hard surface.

No. This is not true.
As far as Zoanthids are concerned, I can say that it is absolutely true.

Amphipods can no more be viewed as a singular monolith than isopods or coepods, both of which harbor harmless and harmful species in their families.

The same is true of amphipods, and the species that is dominant in a couple of my systems, will attack and consume zoanthids that are showing any signs of stress, as well as voraciously consume any aiptasia introduced, so there is an upside at least with these buggers.

Crawls, hops, pogos- however you want to put it, these organisms move about on my glass. They're tiny little dots, about twice the size (at most) of the periods on this page, some of which have two smaller dots of egg sacs attached. If you look closely, you can see their little antennae and pointed tails.

I know you don't know who I am or what I know, but I've been keeping saltwater aquariums for years, and freshwater aquariums for over half my life. I do actually know what a copepod looks like.

You're welcome to look up any variant on "copepods on glass" to see how many pictures there are of copepods sitting on glass rather than free-swimming.

Sadly, it is. Some species of amphipods (including the common gray species) will quite vigorously go after stressed zoanthids, and if there aren't any fish in the tank to keep them in check, they may stress zoas to the point of being tempting food by crawling all over them. I would also be unsurprised if, like cleaner shrimp, they go after food that LPS have caught.

Kudoes to this post.

It bores me to tears to hear semantic games that confuse the Pilgrims and newbies

@Alexraptor
I want some Aptasia eating amphipods. I just ordered 20 aptasia eating nudibranch & one file fish. for $350.

I see that you are located in Sweden. Tell @Lasse hello.

Bonafide Copepod.



I collect them, but some people buy them in large quantities.
Paul,
Send me some of those pods. If I get lucky, we may have a sustainable source of Aptasia Eating Amphipods instead of Slugs/Nudibranchs

This thread amused me no end, I've been reefing for 29 years and culturing copepods and amphipods for just as long. It's great that the barrier to entry of the hobby has decreased significantly, this also seems to correlate with a decrease in the average I.Q level of some of its participants.

I love Gonis and Euphyllia. Maybe too much

Late to the thread, but I’ll have to say please give me this “problem”. At the very least my Mel and Leopard wrasses would feast.

Update - all my amphipods have disappeared from my tank - even from the fuge - over the past 8 months.

The population just dwindled and dwindled until they were all gone.

Not sure what caused it - my tank isn't that clean nor is my sump. I could see the wrasse taking them out up top but the fuge used to have hundreds.
