BRO attitude

My little guy, or girl (is there any apparent sexual dimorphism) is absolutely full of confidence and pride. I thought it would jump straight into the live rocks and stay there for a couple of days, but no... It is more or less constantly out in plain view, spending a lot of time on the glass and doesn't seem to be afraid of anything, including me. I had to poke it a little in order to correct the glass fibre mesh covering the top of the aquarium and instead of moving away, it grabbred hold of the stick and bit it repeatedly before slowly moving to a shell on the bottom.

A lot of the dwarves seem to be that way...the little brown octopus that we have kept (M. digueti) do the same things, often raising two front arms first, then lunging and biting !

Just out of curiousity, how big of a tank would I need if I were to rear the babies? I think once they hatch it wont be too bad, but once they start to grow it will become one. Also, how dangerous are they when they are young? Thanks,

Enjetek,

Are you sure of the species identification? If the species is H. maculosa, you will be able to rear the young, but it is not a matter of how big a tank, but how many. The babies are cannibalistic and will have to be maintained separately. This can be done by making a number of small containers fitted with fine mesh and sinking them in the larger tank. You will need lots of food. For an H. m, small amphipods will work well for the hatchlings. You can also use live adult brineshrimp soaked in an additive such as Selcon.

If you have H. lunulata or some other undescribed small-egged species of blue-ring, you probably will not be able to rear the hatchlings.

Hi Roy,

Just out of curiosity:

In your article on CephBase you describe the Blue Ring's toxin as deriving from a particular bacteria that colonizes the appropriate salivary gland.

My question is - Where does the bacteria come from? Would it be found in the egg? Does momma blue ring somehow impart a 'starter culture' to the hatchlings?

Put another way; if you were to separate the babies immediately upon hatching or maybe shortly before hatching would they still be or become venomous?

Poisonously yours,

TPG

Roy,

What survival rates have you gotten feeding brineshrimp and selcon? Have you used it as an exclusive food?
