shore shrimp

I had the honor of feeding a 15 foot giant pacific in oregon and we fed it shore shrimp that were collected by shoving a 3 foot pvc pipe with a toilet plunger inside. You pull it up and the sucction gets A LOT of shore shrimp. I just stuck my hand in the tank and she took it.:roflmao:

Hey Everyone! I just got what is being called a "dwarf Octopus" from Ebay- he is a feisty cute little guy. First does anyone have one of these and what are you feeding him? Mine has refused little pieces of shrimp and very small hermit reef crabs. Also is there really a "dwarf octopus?" Thanks any help would be appreciated. I have a call in to the seller but thought you all might have a better clue. Thanks sooooo much!!!

Robinspa,
We would love for you to journal your newly acquired octopus. Most dwarfs are O. mercatoris, a nocturnal dwarf species found in the Caribbean and I don't recall another species being offered on eBay. Posting the eBay link and or seller would be helpful to determine if this is what you have.

I have only had luck feeding table shrimp to one of a number of mercs. If you take the hermit out of its shell, it will likely be accepted (my best success with this is to freeze the hermit then take pliers to the shell and extract the whole carcass then put it on a feeding stick or in the end of a pipette and offer it). Freshly killed shore shrimp offered on a feeding stick (a bit trickey) or the end of a small pipette is almost always accepted. Fiddler crabs are readily taken and Cyclop-eeze is a good supplemental food.

Another case for NOT feeding brine shrimp

Laboratory culture, growth, and the life cycle of the little cuttlefish Sepiola atlantica (Cephalopoda: Sepiolidae).

Full article available in the above link.

This is a study of cuttlefish (bobtailed squid) but points out the lack of food value in brine.

ABSTRACT Pairs of Sepiola atlantica maintained in aquaria at ~17[degrees]C successfully mated in the "male parallel position" for between 21 min and 77 min. Over a period of several weeks after mating, female S. atlantica laid egg masses containing 8-161 eggs. At 14.4[degrees]C, embryonic development took 33 days and the hatching phase lasted for 23 days (mean hatching success, 32%). Hatchlings emerged from the eggs at a mean dorsal mantle length (DML) of 1.91 mm and entered a pelagic paralarval phase lasting 6 days. Ten to 20 days after hatching, the internal yolk sac became exhausted, whereupon hatchlings were fed ad libitum on wild-caught zooplankton at a density of -90 organisms/L or with enriched adult Artemia (density, 50 organisms/L). Hatchlings maintained on the Artemia diet all died within 38 days, whereas ~38% of those fed on zooplankton survived to this point, and the remaining juveniles subsequently attained adulthood when reared on a diet of Crangon crangon. These laboratory-reared juveniles matured and successfully mated, but the females did not lay any eggs. Females subsequently died 230-250 days after hatching and 10-19 days after mating, at a DML of between 21.7 mm and 23.2 mm, whereas the smaller males died 265-293 days after hatching (DML, 17.4-21.4 mm). Growth (increase in DML) of S. atlantica had 2 phases. Growth during the first 120 days was relatively slow at 0.05 mm/day (0.043 mm/day in males and 0.055 ram/day in females), increasing slightly thereafter to day 210, after which growth leveled off. These data indicate that S. atlantica has a similar life cycle to other sepioids.

Escargot

Well, maybe not but they LOOK like escargot.

I found a new international market (Assi - looks and very much like an H-Mart) about 45 minutes from the house and shopped their seafood section. Among the new items I found to try were snails in a large bucket and a small amount of water. I realized when I got them home that I did not know if they were fresh or saltwater snails :oops:. I put one one in each environment and the one in the saltwater started to crawl around the cup in a normal looking manner (and did not react to the salt like a salted slug :yuck: as I half expected). The one in the freshwater drew itself tightly into its shell so into Monty's old aquarium they went. They were obviously saltwater as the ones I have not fed out are surviving and active after two weeks. These have a particularly large opening at the mouth of the shell and the shell is semi-opaque when empty like the escargot snails served in restaurants (I have no clue as to the proper name and Wikipedia says the kinds used are usually land snails). All three octos will eat them within 24 hours where they leave my others mostly alone (Monty seems to take a liking to the others as I have mostly empty shells in his tank now).

I also picked up shell-on and shell and heads-on shrimp, frozen cuttlefish :oops:, abalone and fresh, uncleaned squid. This is the first store-bought shrimp Monty has taken (we are convinced he is insisting that food has a shell and I am not finding the shrimp shells so I am wondering if he is actually eating them along with crab shell - crab claws I find but not the body or legs, very odd). The twins will begrudgingly eat the abalone and we will try to entice them to take it more willingly but the squid and cuttlefish were rejected (which was fine by me really).

I also found live conch and picked one up to try a rescue. I am not sure if it was dead when I bought it or just too far gone but when I got it home is was definitely dead. We cut up the meat and froze it but I don't think it has been offered yet. I will try rescuing another next time but will take a bucket of saltwater with me and make sure I actually see movement.

Two ways. first the store you buy them at will have them marked as saltwater. Two, if they are living in saltwater then they are most likely saltwater snails. If you find them in a freshwater then they are most likely not saltwater snails.

There are some that are brackish water as well and can usually survive in a marine aquarium. I have bought snails at the international market where the sellers had no idea (or not enough English to tell me) so I bought some and tried one in fresh and one in salt. The snail in freshwater did not come out of its shell but the one in saltwater became active. I put both in a spare saltwater tank along the others I bought for a couple of days. All survived and were active (including the one that would not come out in freshwater) so I suspect they were accustomed to brackish water. After observing them for a couple of days, they were distributed to the tanks.

I suspect a similar test on a freshwater snail would cause death or worse. Land snails cannot tollerate salt so I am not sure if a freshwater only snail would start to dissolve or not.

Blue Crab Claws from Seafood Market

A couple of weeks ago we saw live blue crab at the International market we visited. I wanted to get one for Diablo but they were really too large and LMecher has mentioned how messy and tank impacting feeding a whole crab is. However, Neal looked in the bin and made the suggestion that we try to collect just claws that were already removed. We were able to get a dozen or so and brought them home. What a great food offering! Even LittleBit can handle a full claw and takes it very enthusiastically (an then I have trouble getting the empty shell out of the tank as both octos will try to prevent removal) but what we have been doing is giving the full claw part to Diego and the large attached arm part to Little bit. It takes them awhile to eat the meat but the claws are completely empty when they are done and there is virtually no mess to clean up except the hollowed out shell.

We went to two different Asian markets today to try to get more (the original market is further away). Either they had been shopped out, don't get as many as the original market, or the end of the season is near because there were fewer crabs and way fewer claws but we still came home with some octo food. As with the first batch, we froze all but the one we fed today.

We also made a seafood rescue* attempt since our rescued* conch is still doing well. This time we found live abalone and brought one home to see if it would survive (also brought home some clams to put in the octo tanks as optional food/clean up crew).

*Note: I do eat seafood and the term rescue is a bit tongue-in-cheek and more of an experiment of what will still survive than any intent of rescue. Since we don't know where this animal came from (it was not posted) and different species live at different temperatures, there is a chance our tank is too warm.

PS
Abalone not doing well. I believe I have a correct ID as a southern CA/Baja MX species so the water temp is fine but the brissle worms and pods were all over it tonight so it is isolated in a bucket for observation (it was still alive but not very responsive).
