My cute little yellow boxfish (Ostracion cubicus)

[MakerOfMonsters]

Apparently these fish grow to 45cm and change to a grey colour when mature. I really wanted one but it would probably grow too big for the tank and hassle my other smaller fish. Don't really want it poisoning its tankmates either. Research it up first guys.

[ChrisRottweiler]

Would have loved one if they couldn't potentially poison my tank. Too big a risk for me. Lovely fish though.

[gamezonic]

i thought they were rare

[OMGLouiE]

mine is not wanting to eat :( i dono what to feed it...

[raulgocubs]

omg that is the cutest fish ever lol!! I'm buying one tomorrow, I saw it at the fish store omg omg I can't wait

Interesting. If i remember correctly, some country's navy is researching on the design of a submarine by studying the boxfish. They wanna come out with something to model the shape of the boxfish (more comfortable chamber) but can also move through water with ease. But as far as i know, boxfishes are slow swimmers & not as aerodynamic like sharks, which has shape like a topedo (aerofoil shaped).

@seuquin the boxfish can cover 2 meters a second and the design has been used in the design of a car

@Bowsersshell COOL!!! I observed one before at the aquarium, but seems that it looked a little clumsy. Maybe i should give it a fright so that it can push itself at full speed :)

[FitchIsDead]

Be carefull!! When it grow up... It'll eat your shrimps.... and your tank is too small....

[rolensmash]

boxfish are adorable but tricky. you must feed them so that they do not gulp down air and if it dies it will release toxins that can completley destroy a tank's ecosystem and lead to a collapse. if you have the money though and are willing to take the risks these can make some of the most colorful and peaceful fish in the entire aquarium trade.

Saw one while I was snorkeling in Fiji the other week. LFS has a few from time to time.

[xXwannabeguitaristXx]

eeeeee! That's really cute :)

[sedlfel]

haha i want one

[BrettBarnett10]

that is the cutest thing in the world

[tastythighs180]

how can you keep him in a reef without him eating everything?

[bonsomei]

great idea with the yellow scissors, If your wear yellow it's probably the same :)

[giant2na]

that tank is much too small, the cubicus requires upwards of 100 gallons.

[cwpridedb5]

he is so cute we just got one yesterday.

[ji3200]

how is your boxfish doing??? did you have any trouble?? boxfish kill most of my fish after he spread toxic into my tank when he died. how about you???

[GrnApple02]

Very Cute! I'm looking to get a Hawiian/Thornback Cowfish. I know it's not the same but they are very similar. I was wondering how big is your tank?

[softballkpab13]

usually you need a 150 gallon

[redmojoill]

The poison in the fish actually comes from a type of toxic algae that the boxfish eats....if you dont have that type of algae in your tank then you have no worries if stress or dying (it wasnt luck).....

[HunterJumper4466]

Are they hard to keep? And how big for a minimum tank size?

[kvilanova]

hmm i insist, not at all, mine is ok and my tank is crowded.

if the fish is not stressed then there are no worries, if they die stressed they,ll poison the water other wise not.

seen it on a friends boxfish who died and nothing hapend to the tank, maybe just luck

[oyanezg]

[TheCatAteMyShoe]

Very adorable, indeed! I love it how she is so happy about being fed. She's so friendly, too. What's her name? Or is she a boy?

[kellyslater87]

why dont you hand feed?

why are they hard

[Steve62341]

wow that is a really awesome fish how, much was it if you dont mind me asking.

[jk2000]

OMG! He is so cute! Are boxfish hard to keep?

[ohsoscreamo]

Very hard.

[oyanezg]

No not at all, just carfull cause they are toxic if stressed 2 much.

the sucker who posted very hard is a dick or retard , thats why is so hard for him

[Seishinbunretsusho]

they do emit poisons from pores in their body when stressed or dying, but don't go and call someone a dick unless you know what you are doing. they are very difficult fish.
