    Hello again everyone. As some of you know my first O. Hummelincki died a about a week ago:sad:. I am trying to get another opinion on wether or not I should give it another go. My water parameters are as follows:
    Ammonia- 0
    Nitrite- 0
    Nitrate- 10-20
    PH- 8.2
    S.G.- 1.023
    Temp.- 78
    Copper- 0
    My friend at the LFS has a baby Hummelincki in, and said that he would replace Ocho (deceased octo). I'm just curious if my water quality is up to par for a Hummelincki and if you guys think it wise to give it another go.

    i would say it is fine. right now my water is worse then that and mine is doing fine. although i'm not saying leave it like that. just do a few water changes. I just haven't had a chance to do it in about a month...

    Believe me, you're not the only person that's been discouraged by death.

    its probably not even ur fault, u rparameters arer fine. although octos prefer a 1.026 SG, i dont think thats the cause. every LFS ive been to kept their octos at 1.023-1.024

    I am currently drip acclimating my new Hummelincki. He/she is curled along the side of the bucket, normal acclimation behavior? How long should I drip the little guy for?

    Drip for a good hour. Watch you keep him covered. I had one escape within seconds of my taking my eyes off the container.

    He has been in the tank about 30 minutes and is now covering my clam (assuming he is eating it) Watch out Hermits and snails :smile:! The lights will be off for the next 24 hours, but when they come on should I just use the actinic blue? Or can I use my 10,000k daylight bulb too, or is that much light gonna cause stress? They are power compacts.

    Congratulations!

    Your lights should be fine. If for some reason your octo doesn't like them, just use one or the other. Let us know how it goes.

    I believe he is a male so his name is now otocon or otto for short . He is spending alot of time in his den. He will come out when I drop a fiddler crab in the tank but then pulls it back in. He seems very shy, considering my last one would spend alot of time in the open and cruising the glass. Which behavior is more normal? Both are Hummelincki.

    Normal for a wild caught would be hiding but placed in such a way as to observe you.

    Yeah he is in his den with one eye peering out at me. He only comes out to take a fiddler crab. when I get close to the tank and look at him he doesn't hide, but flashes colors at me. In three days he ate 2 fiddler crabs, 1 coral banded shrimp (didn't plan on that), and 2 hermit crabs. Only thing that worries me is his color sometimes he will change to grey almost white.

    My only experience with hummelincki is a wc that I hosted for 7 months and a brief encounter with one in the wild (and my new little one that has been with me for less than a week). I think you will find he will become more interactive (unless he is a she) the more time you spend near the tank. However, I have also kept mercatoris and the six sibblings I raised were all very different. One would interact nightly and come out at feeding time even if the lights were still on, one hid for months but would finally take shrimp at the end of a pipette and the others were either extremely shy and not seen for days (sometimes weeks) at a time. The captive bred from that group were not at all interactive.

    The grey does seem to indicate stress or possibly age but Octane would show that color and then bounce back. Anytime he stayed gray for a day I would do an extra water change even though I did not detect anything unusual. This always seemed to help. I can't say why but he would perk up appreciably. You might try adding an airstone in a tube (to keep the bubbles near the top) as I half suspect they need more oxygen exchange as they age even though there was an excessive open flow in my sump. Also, full salt vs reef salt (1.026 vs 1.023) and a PH closer to 8.4 are recommended and where I keep my octo tanks.

    He will only turn grey for a second then goes back to "normal". I'm just worried my lighting is too intense (65 watt power compacts with an actinic blue bulb)

    try reducing the light. As he is new to the environment he may be feeling some stress. Let him "chill" for a bit then experiment with light levels.

    Good question. In Octane's tank we ran one 65 watt about 18" away from the top of the tank. In the new tank we put in two 35 watt running long ways so it is like a single 35 watt and Serendipity seems to think it is too much light. She has created a den under the rock in the sand (Octane never messed with the substrate but there was a UG of sorts under his sand). Initially she came out with the lights on but the last two days she has not ventured out of her den until at least one side was turned off. We are thinking that they may be light sensitive when young and will probably alter the left and right sides for awhile (I have to get another timer first).

    If he is only greying for a short time (I forgot you said he is a baby), I don't think is it suggestive of a major problem.

    I put a much lower wattage, regular flourescent light on there and still no luck with him venturing from his den. He no longer will accept krill. He will take a few bites and then throw it out. But he will eat blue leg hermits, fiddler crabs, and shrimp (all live). I usually drop the fiddlers near his den, should I just let him find them on his own? How long will they live in salt water? I figure eating is more important than him coming out alot. But he always has one eye on me, watching. (kinda creepy)

    And he is only turning grey when the lights are off now.

    Shea,
    Serentipity is very shy too. I found with Octane (who was adult and never very shy) and with SOME of the mercs that just making myself sit in front of the tank for at least 15 minutes EVERY night (whether or not I could see the octo) seemed to be at least part of the key to being accepted. Serendipity stayed out the longest yet with me tonight and actually came up to the front. When she went back to her underground den, I left but saw her out again and just sat while she hunted. She will allow me to stoke the tank and came up to the corner I was "petting" but would not follow my finger to the front. Since she does not appear until after the room lights are off, we have been using only red light on one side of the tank (her tank is split into two different tanks with tubes between them and an opaque black top with light cutouts so lighting one side really only lights the one side). Until she starts coming out with the room lights on, I think we will leave the one side dark in the evening but leave the lights on in the day for the few corals and macro that need it. If you have a standard screw in fixture, there are red LEDs that will fit as well as using red velum over a light or over the cover (Humm, now that I have said that, I think I have a piece that I can put over the light opening - glad you posted!)

    My experience with fiddlers in the tank is for them to last about two weeks, but usually they are found and eaten before that time.

    The live along the ocean shore , burrow into damp sand, so they don't really live in the water full time.

    I've personally found red light works quite well with the littler guys makes them feel that it's night time. Obviously if you have other things in the tank that need light then you would need to have some light part of the time. But maybe you could reverse the light cycle so that you turn the time when your at work into daytime and then have the red light on when your at home, you should see more activity out of your little one, however it is sometimes slightly harder to seem them in the red light...

    Thanks Perky,

    When you mentioned "little" ones are you referring to day active adults or nocturnal pygmies? I have raised three generations (but only from one octo) of pygmies and have learned to squit (but not photograph) with the red light but they never really acclimated to even room light (one was marginal). Hopefully both Shea's little guy and Serendipity will acclimate to brighter light over time. My adult hummelincki (and I think Shea's previous adult) did not have issues with being daytime active under tank lighting but I have no clue when or if this will change (or if it is male/female dependent). The tank is near a window in a room without curtains so trying to reverse the day cycle won't work in my case. We are experimenting with the half red half white to see if that reduces the light enough to encourage activity earlier in the day but she has not shown up yet tonight. We both have had our little ones for less than two weeks so the jury will be out for quite awhile yet :wink:
