Probably a silly question :)

Hey Guys,

So, I'm going to probably get an emerald crab once my tank is done cycling... Do I need to build rock above the water for him to climb on? Does he need air?

Just wondering

Thanks, Andrew

No air needed!

 

[TCReefMan]

Awesome!

 

[Mhay]

Enjoy your crab!

This.

They have gills. It's those rubbery things that get in the way when we eat fresh crab. I'm pretty sure the anatomy is the same.

I thought about an emerald crab..but I have a 20L and is becoming a nano reef slowly..would this crab be fine in this tank?

 

[TCReefMan]

thatreefguy22, I'm putting mine in a nano... They are about the size of a quarter. I positioned my rock to make several caves for him to hide out. They eat bubble algae too apparently

I don't have a lot of hide space, but I have more live rock in my sump I can use for the tank to make more caves. And, do they only eat bubble algae..or will they scavenge like all crabs do? I wouldn't want coral to be munch food for crabs...LOL

Just be sure you keep him well fed. If not, it could turn to your livestock for food. Actually, even if it is well fed it could still do that.

So, what would be a cool addition to a nano reef? That is sure to be safe around corals

stock so far for my 20L:
x2 clowns
x1purple/yellow dotty back
green torch coral
violet zoas
green mushrooms
x2 turbo snails


What would be another good addition?
I am looking on divers den.

20L = 5.3 gallons and for a 5 gallon tank you sound pretty overstocked as it is

 

[ReeferBill]

I think he means a20 gallon long tank!!!!

 

[ReeferBill]

I would stick to small fish like clown gobies , neon gobies , tail spot blenny , anything that does not need more space and has a small impact on the biological load of your set up...

+1

I really, really hope so. He's repeatedly said liters itt.
If it is indeed a 20 gallon, then I'd highly recommend a neon cleaner goby. They have short life spans but are amazing fish full of personality, you could also get a cleaner of fire shrimp.

I have about 25 gallons haha, 20L=20 gallon long extra 5 gallons from sump.

I wouldn't suggest a cleaner goby, they only have short life spans in our tanks, in the wild they can live a long time. this is one fish that should be left in the ocean till more data on what they need to survive is made.

I have an emerald crab in a 20H with 2 ocellaris clowns, court jester goby and a ton of snails. he's really good at keeping the rock clean, but he does occasionally pull off a zoa polyp from the colony if it is loose. pretty nifty critter to watch. just dont stick your hand near his hiding spots. they fear no hand. I shrieked like a little girl the first time I made that mistake :lol:

So, it should be okay for a mixed nano reef? In my case, I'd have to take rock from my sump to make more of a rockscape to make more places to hide out.

I'd really enjoy having him in my tank, as long as I can feed him with something so he won't go after my corals. I have a pretty good start with corals. But the sight of an emerald crab would be sweet for me and everyone else.
