Do you know its origination (body of water)? Is it nocturnal? A quick guess from the shorter, thinner back arms and long front arms would be an Indonesian nocturnal animal in the macropus complex like Puddles

I supplier told me "she" came from Philippines

why do you think it's a "she"

and by knowing that "she" come from Philippines, can you determine the species?
what would be important to know about her?

right now we are feeding her small pieces of shrimp, and silver side, 'she' love both
but she is more active in the morning or when the light is not as strong

thank you very much for your help!!

mreef,
The Philippines would fit for the little macropus but neither of mine were out after full light and both were most active around 3:00 AM. The word Puddles in the above post is a link to his journal and photos. Look for white spots when she is aggitated and green fluorescence that will sometimes show as small spots on the mantle and sometimes are quite bold as in the link to Beldar's journal. To determine sex, observe the third right arm (clockwise from the eyes). If the tip is curled most of the time, that would be an indication of male.

I'm not an expert and by no means the best person to ask as there are others with much more experience than myself. I was just taking an estimated guess from what I saw. Like D said, check the third arm.

she really look like "puddle"
but she seem to be a lot more interactive in the day, she always play around on the morning when the light is on, and will do it a couples of time during the day too

but when she is tired she will do like 'puddle' and be a puddle lol, when she does that she will become almost all white/gray, if I come close she will become reddish

I tried to find information on her species, but I didn't find anything
she look to be about the same size as Puddle, and by reading the post, this would be her adult size... hope she is not too old

how big should her aquarium be?
and since they are so intelligent, should I put something in her tank to make life more interesting than just live rock?

at what temperature should I keep her tank?

and I know male and female die shortly after reproduction... but if they are no reproduction, how long can she live? (if she is a young adult)

I'll try to look at her closely to see if I see spot on her this morning... to confirm if she is like Puddle

thank you again for your help :smile:

So what did you see that made you guess female?

mreef,
It was my fear that if I had the species right, she is adult, partially from size and partially because she is out during the day. The daylight activity can be discounted somewhat to acclimation (full acclimation usually takes about 2 weeks IME). At the time I kept Beldar, we had two others among members and both would appear during the day from time to time (Lennon has a journal here but Thales only made comments on Zod in Bel's journal)

To find more photos on this apparent species, Google Octopus luteus and look for diver sightings. Using Norman's Cephalopods A World Guide this is not a correct call on the species but seems to be the tag divers use when they find it (we see this a lot for certain species). There are quite a few animals in the macropus complex and many are simply marked "sp" (for species not identified). Thales and I have both found one in this book that is closer in size and looks but it is marked sp 10.

I believe all the macropus complex animals (there are even some in Mexico) are warm water animals fo nothing below 72 with 75-78 likely being best and for water quality nothing above 80.

If she is female, you will likely see her brood soon. Here is the part of Bel's journal when she started to brood. If you read backwards you will see that I thought she was male for quite sometime as I would see her arm curled a little when she was younger. It also took awhile for Puddles to mature but at the size of your new one, I expect she is sexually mature (different species mature sexually at different rates).

Females will brood. It does not matter if they have mated. If they have not, the eggs will be infertile (as appears to have been the case with Bel). At the assumed age of this one, and the assumed abundance, she will likely have mated but we have not seen hatchlings from this species that I recall. Sadly, it is a small egg species and trying to keep any small egg alive through the palegic period (palegic for about a month) has not been achieved in home aquariums and very little success in large flow through systems in labs or public ones. Bel's journal will give you an idea on what to expect. I recently read that removing the eggs within 24 hours of being laid may prolong life a little and stop the brood behavior (den isolation and cessation of eating) but have not had the opportunity to experiement.

I didn't know that if there were no reproduction that the female would still lay eggs :frown:

well today, my Little Miss Puddle didn't come out to play like she did the past 2 days... she was sleeping under the rock, and when I try to make her come out, she just move an arm like she was saying " leave me alone, don't you see I'm sleeping!!"

so I don't know if she just start her normal way of being active only at night or if she will brood soon...
she didn't eat today... so I put a little crab with her... maybe tonight she'll catch it

.... I don't want her to brood.... I want her to stay alive longer!!
