hey everybody, I have a new octopus for myself after about two years of asking for advice and info :smile:

Anyway his name is kraken and he is a little o.bimaculoides.

here is his tank set-up:

Aquarium- 30g tank
Filtration- CPR Aquatics skimmer/bio-filter combo
Structure- a stack of live rock on one side of tank with scattered wavy-top shells for dens.
Tankmates- 2 small brittles, 1 avanax, 1 small sea hare, a couple cleaning shrimp, 2 sculpins, 4 turban snails, and around 2 dozen hermits.
pH levels- "dark blue" on the test or alkaline

yeah i know its only a 30g, but he is very small right now so I will move him up into a 50g when he starts to get bigger or maybe just let him go.

the hermits, shrimp, and the turban snails are working as cleaners/food and the sculpins are very suttle and either feed off extra waste or some tablets I have.

the sea hare eats algae and the avanax is just for show. Also, I would like to know if the care for avanax is the some for sea hares because thats what I have related it to so far. If they are toxic or for advanced keepers only I will quickly send him back he was sticking onto a piece of live rock I brought in and he is very pretty so I just kept him there.

Currently kraken has found a shell to his liking and has littered its front "porch" with empty hermit shells. when we stick our heads to close he reclines partially in but otherwise he is just looking out at us from it.

he is very cool and I would GREATLY appreciate comments and suggestions! Thanks in advance! :grin:

thats it? OK, if there is not much response than I am going to guess my tank is good :)

Oh, I was also wondering if I should add some pvc pipe for him to mess with since I heard they like it.

comments are appreciated :)

Sometimes we just get very busy and don't have time to reply to all posts!

Welcome to kraken!

A thirty gallon is OK if you have the option of a larger tank later (which has to be cycled) or returning him to the ocean.

A sea hare isn't really recommended, is somewhat risky.

I'm not familiar with that particular filter/skimmer.

You should be testing your water for sg (you'll have to top off with buffered RO/DI water), pH, nitrites, nitrates and ammonia.

Yes, he might like some short lengths of pvc pipe. Try also plastic baby toys, legos, etc. Some octos like them, some don't.

well I used fresh ocean water but I still have been testing pH and nitrites.

Should I have a test kit for all of them?

ya sorry for being so impatient...i see now that there are so many people posting now a days that your threads aren't immediately attended to anymore...

Yes, you need a test kit for all of them, because even with ocean water, you are going to have a cycle in your tank with the octopus. You will still need to top off your tank with fresh water because the water is going to evaporate.

When water evaporates out of your tank, only the fresh water part of the water evaporates into the air, the salt is left behind, raising the salinity of the tank's water, so you need to add fresh water to compensate. To try an experiment, leave a puddle of salt water in the sun for a day, you will see the salt left behind. That is why you need to add fresh water NOT clean ocean water... Hope this explanation helps...

Marineboy lives near the ocean and gets to collect his own specimens. His vast experience is with seeing octopus in the wild, not with keeping them in captivity - he is learning like we all are...

I draw a line with permanent marker on the outside of my tank at the water level. Then I add water when it is below that line. After salt water changes, I always refill to that line.

You needn't worry about the permanent marker on the glass: a little bit of alcohol or acetone will take it right off!

is it ok if my salinity is at 1.023 instead of 1.026 like the care sheet reccomends?

also, my test showed readings of small amounts of nitrites in the water so I followed what it said by cleaning the sand on the bottom and doing a 5% water change. is there any other methods I should take to get them back to 0? it also reccommended extra aeration.

thanks for your help guys :)

You'll probably have to rely on water changes to keep your water parameters good.

Yes, 1.023 is OK, but you might aim for 1.024-1.025.
