6th ave nudibranch

[dzhuo]

everytime i stop by 6th ave, they have those blue, purple and pink nudibranch in their shrimp-tank. some of them appears to have been there for a long time. aren't those impossible to keep? how come they can keep them alive for so long? or are those the easier to keep kind?

anyone know?

Maybe the just keep on replenishing the stock? Its not like theres a tag on em to let you know its the same thing that you saw for the past couple of weeks...

there won't be any tag on them, that's for sure. and they could be replenishing their stock constantly but only if there are buyers. i can't imagine (especially for 6th since they are always profit first) they keep restocking stuff they can't sell everyweek. anyway, do you know what kind of nudi those are?

thanks!

thanks delso but it will take me at least a few days to click through all the links to find the match. so i turned to google and found what 6th ave has:

http://www.versaquatics.com/techniqueinmaintainingaquaria.htm

but the site doesn't tell me the scientific name or care requirment of it. it does say that this is actually not a slug, it's only a close relative so i wonder if it's actually easier to keep?

thanks!

As long as its not an Aeolid nudi' meaning coral eating..

But if you want a slug/nudi that's easier to take care of I'd go with a lettuce nudi, Ornate Elysia, Sea Hare... most will eat byprosis, derbesia, caulerpa...

but if you want something nice looking. the blue stripped nudi ( chelidonura varians ) will clear your tank of flatworms and red planaria

Hypselodoris bullockii

I would stay away from this, and all nudibranchs as they all have a very specific diet, meaning they will only eat one thing, I believes these eat sponges. Now since you probably would rather have sponges in your tank, don't get one, not to mention even if you had many sponges this could wipe them out in short order.

6th avenue does this kind of stuff with animals that are certain to die, which is why I always try to steer people away from them

more resarch confirmed that what 6th ave has is hypselodoris bullocki which only eats sponge. i will avoid it. you mentioned ornate elysia and chelidonura... are those easier to keep? my tank is only 10g and it doesn't have much algae at all. will they take supplement food?

 

[sfsuphysics]

Nudibranchs will only eat one type of food, many will eat only one species of one type of food. Stay away from ALL nudibranchs, you won't be able to hook them on a manmade food, the only exception being those that eat pests, aiptasia, flatworms, etc , and once that food source is gone they will starve to death. They are colorful they are pretty but they shouldn't be kept as pets.

An exception is the "Lettuce Nudibranch" but that's because it's not really a nudibranch, it's a sea slug, this even has issues since strong currents (often in our reefs) are enough to whip these guys around.

The closest thing to a slug I had was my seahare, fed it nori to supplement when algae was scarce.. mine was about 4inch which would be way to big in your tank and not get enough food. In my 100 gal he had enough food to suffice. As SFSUPHYSICS suggested most nudis are nice to look at but extremely hard to keep especially the diet specific ones... I don't know maybe a dwarf sea hare ( but don't know how big the get ) or a tiny lettuce nudi/slug but you have to have a bunch of algae in your tank... Don't bother with the ones that eat flat worms as they are diet specific and once you run out of flat worms , there goes your nudi as well.
