I've been trying to offer Megamind food and see if he gets used to me so he won't dart out of sight all the time. He stayed out longer today watching me or maybe he was just sleeping. I got another nice shot of his tentacles since he likes sticking to bottom left corner of the glass a lot. And his bulgy eye came out too, observing me I think. I was surprised that he actually gave me time to manual focus before leaving but once he left, he was gone gone. I could still see him under a shelving rock, but my camera couldn't. Oddly enough his eye didn't look at all like in the previous shots but I guess that's due to their ability to change color/texture unless there are two octopuses which I highly doubt. Here's Megamind. DSC_8014.jpg

Looking more and more like O. mercatoris. The little "eye lashes" under the eyes are considered one of the attributes of this (but not ONLY this) species.

So I was dangling a small live crab in front of Megaminds cave, I could see him watching me from the small gap and he waved two tentacles out of the hole next to his cave entrance. He did the waving tentacles twice, I looked down for a second to take the lens cap of my camera and the sneaky little guy grabbed the crab and ducked back I to his cave with it. Lol. I did manage to get a picture of his ever watching eye, I'll post it later today. He looks less tiny than when I first spotted him. He was the darkest red I'd ever seen him when he snuck out of his cave to snatch the crab, I wish I'd gotten that picture :P I wonder why though... I've read they turn white when they become scared, I've usually seen Megamind red. I'm gonna read up on what we know about specific color changes (besides obvious camouflage). He's eating about 2 hermits or small crabs a night, I guess any appetite is a good appetite?
I'll give more updates soon!

Eating is always a good thing. How much and how often is not well established. My personal opinion is that the frequency depends a lot on if it is a warm or cold water species AND the age. They grow very rapidly in the 4-5 of months (guessing Megamind to be around 2 months) so my thinking is, give them as much as they will eat daily.

You can feed live food throughout their lives but many of us do not have regular access to live. Food size does appear to matter and my best successes with dead food is to begin by offering eye sized pieces and slowly increase to about 1/2 mantle size as they adjust to the accepting dead food. Live food should not be larger than mantle size and I suggest about half that. The mercs I have kept have all been less adapting to frozen than the larger animals but have learned to eat freshly killed (they don't seem to be able to catch them once they are adults) shore shrimp and frozen fiddler (or any small - be sure there is no smell when freezing) crabs. I have also had good luck feeding young and very old animals (they only live 10-12 months) with frozen Cyclop-eeze but it is no longer available to hobbyists because of a failure at the collecting source. You can try a variety of fresh/frozen marine foods including small pieces of fish, clams on the half shell (larger animals can open them but I have not seen the dwarfs able to do this), crab claw meat (I freeze freshly collected blue crab claws - NOT THE WHOLE CRAB then extract the meat and thaw before offering). Claw meat can be extracted and offered on a stick (you can try hand feeding once he is fully acclimated). Crabs offer the best nutrition and should be a mainstay of their diet. I have not had any luck with abalone, recommend avoiding oysters and mussels because of the mess. IME, thawed frozen scallops seem to be accepted once and then ignored.

A tripod and remote firing device (if you camera can accept one) are recommended :biggrin2:

sorry for the super late update, my internet was down for a few days. here are the pictures ive taken of Megamind. He's eating well, I catch crabs and small shrimp from where i got him to feed him. The crabs are slow and he catches them quickly but the shrimp are quicker and take him longer. I've noticed he has an appetite for my cleaner snails, from Ocoa Bay like himself, so I throw him in a few sometimes. DSC_8040.jpg DSC_8060.jpg DSC_8064.jpg DSC_8065.jpg

oh also I received an email from one of the forums I'm a member of and it spoke about using old phones as cameras to view your fish tank from work or anywhere. This seemed pretty cool so I installed the app on two old android phones and, though the video isn't the clearest, I see a lot more of Megamind than I did before. Pretty handy having these old gadgets sitting around ^^ If anyone's insterested the app is called "at home video". I'm not sure if that one's available for ios but there are also several ios and cross platform apps that do the same thing.

Just happen to have a couple of old phones but not sure of compatibility ... will have to investigate :biggrin2:

Hey everyone, here's a short update :grad: Megamind is eating well, he's settled into a little nook inside some live rock but he's facing the front aquarium glass so I see him all the time now. He's less shy, won't accept food yet (I've opted for just feeding him live food straight from Ocoa Bay which he accepts readily). He'll let me observe him and he'll observe me back :sink: but when he gets tired of looking at me, he kind of halfway drops down from the nook and pulls up any shells and pebbles from the sandy bottom and then slides back into his nook holding the shells and pebbles in front of his peeping hole. I took some pictures, I've realized what a lousy shot I am with moving creatures since my macro lens is only manual focus. And I thought I was halfway decent :roflmao: lol
You can tell in the photos when he decides he no longer wants my prying eyes staring at him. I wish the photographs were better though, the light is very low so I end up needing to use slower shutter speeds and my shaky right hand is extremely annoying in these situations... :troll:

I've had to buy an extra long charging cable for the phones but they were pretty cheap. I find it pretty useful so far, I've seen many things I wasn't supposed to see lol. For example, I've realized that my cat has a habit of jumping on top of a shelf that's on top (about 3 feet above) of my other tank, where the tank lights are hanging from. Today she thought it'd be a great idea to continue her shelf jumping prowess and she fell inside the tank :shock: now i'm kind of worried for both my tank and my cat since that's my zoa filled tank and I know zoanthids are pretty toxic. Today is maintenance day anyways so both tanks got water changes and I ran some carbon through the one my cat fell in. Cat got a bath and I think she's in the clear for zoanthid poisoning since it's not like she ingested any zoanthids or had any cuts, I'm just kind of :bugout: when it comes to all my pet's health be it a four-legged mammal, a reptile or a fish. My house is like a zoo, but then why be a vet if I can't have my own aquarium and petting zoo :roflmao:
