Algae eating Elysia Nudibranches for sale

[MarsRover]

Hello All,

I have a handful of elysia nudibraches for sale.

They've maxed out in size in my tank at about 1 to 1.5 cm before replicating.

They are very entertaining little ones and replicate very easily.

I can sell 10 for $100 + overnight shipping while supplies last (I probably have about 50 to sell today). If you are in the LA area i am willing to do local hand-over.

i wish they'd eat my bubble algae

So i can neither confirm, nor deny that they eat bubble algae. I try to keep mine to a minimum just by carefully pulling bubble patches without popping them. That said, i have let some grow on the main rock i have that the elysia seem to be spawing on and i noticed some of the bubbles have been deflated.

in the first two pictures of my second post, you can see the deflated bubbles.

Are nudibranches bad for a reef system, ive heard mixed reviews about them?

Nope! well... some are... it depends what you want.

If you want zoanthus (you probably do...) then keeping zoanthus eating nudibranchs is a bad idea. (these Elysia are NOT zoanthus eaters)
If you want aiptasia (you dont....) then keeping Berghia Nudibranchs is a bad idea (these elysia are NOT aiptasia eaters)


For these particular Elysia, if you want slimy green algae, don't keep these guys in your tank!

If you don't want algae, these guys are a great cleanup crew. They are herbivores and only eat algae! Though, i have found they tend to graze on microalgae and NOT macro algae as much. I've only seen one or two in a small patch of hair algae i keep in my tank and there has been no clear evidence of them eating it at all.

They do however go to town on the green microalgae that grows on rocks at the top of my tank only a few inches away from my 400W Metal halide lamp and on the algae that grows on glass.

I am starting to believe these particular Elysia eat bubble algae as well. I have been noticing more and more my little bubble algae population is slowly having an increasing number of deflated bubbles!

The hardest thing about nudibranchs in my opinion are that they all tend to have a very particular diet. (i.e. each kind of nudibranch only really eats one or two types of things. very picky!). This can be either good or bad depending on what type of nudibranch and your desires for your tank.

Any guess on what eats hydroids? What is lifespan and since they are small will they starve?

Not a clue! I'm a mechanical/aerospace engineering, not a biologist, unfortunately. I don't even know what you're referring to exactly as a "hydroid"

All i know about these nudibranches is they grow very fast, reproduce fast, and, for nudibranches, move very fast. they don't do the usual sea-slug/snail type mobility as much as they do the inchworm type of motion. This makes them mega fast but sometime prone to getting blasted off a rock by a powerhead and floating around as a small green sphere for a while before landing somewhere else

haven't seen any die yet. but they are very small. I guess that could be a plus in the sense that if they do die they won't impact your tank like a larger slug might.

Do you know what species of algae yours eat. I've heard that they can be quite picky and is like to be sure I can feed before I buy.

 

[MarsRover]

not sure unfortunately. Haven't been able to get a good ID on them yet. They do eat the green microalgae that grows on glass. not sure if that will help you :/

Got a batch available?
