The crabs have molted!

About 3 weeks ago both of my crabs finished molting. It took them roughly about a month and a half from the time when they found their spot, stopped moving/eating/drinking, until they came out of the old shell, consumed it, and finally resumed their normal behavior.

The male (Lucas) dug himself a tunnel under the sand, which he then collapsed so nothing will disturb him during this sensitive time. But, for some reason, the female (Luna) felt confident enough to go through this process out in the open. Which is why I was able to take the following two pictures. I decided that my desire to document this process was not good enough reason to disturb her in this critical process, which is why the pictures are not very great. She also settled into the very back corner of the enclosure, behind a log, which also made things more difficult.

In the first picture, you might say there are two crabs. But, in reality, only the farthest one is a crab, the other one is its discarded shell.

In the second picture, the empty shell can be seen on the right side under the log, while Luna is on the left.

The pictures don’t do a good job showing how dull the old shell was compared to the new and shiny one (I wish I had thought to do BEFORE and AFTER shots). Both crabs came out of the molting process looking like they spend a month buffing out and moisturizing their shells.

Since they’ve finished molting, they’ve both been ravenous, eating anything and everything. This is quite different than their normal pre-molting behavior, when most of the food would go uneaten. I wonder if their appetite is going to continue this way or if they are simply replenishing their energy reserves.

Carpobrotus edulis – UPDATE

A few months ago, when I discovered and introduced this plant into my crabitat, I was super excited and was looking forward to a nice looking habitat.

Unfortunately, the plant only lasted about a month before the leaves started turning brown and soggy. I believe the high humidity and constantly damp sand to be the culprits.

And so the search continues. I’m looking for a tropical plant that likes to stay wet but does not mind a nutrient-lacking sandy soil. I’m not even sure such a plant exists…

Live plants for crabitat

Looking around at crabitats online I’ve noticed something a bit peculiar: there are rarely any live plants in the habitats. Most of the decorations are plastic vines from the pet store. I am a firm believer of making the environment for pets as close to the real-deal as possible. For crabs, this not only means emulating the temperature, humidity, and substrate, maintaining a proper daytime/nighttime balance, but also providing the vegetation and foods they encounter most often in their natural environment.

So I started looking into possible candidates to try planting in the crabitat. Luna and Lucas said they’re ready to go green!

While researching and trying to find tropical plants that like high humidity and temperatures, I was at the beach one day and literally walked all over the perfect candidate. Seriously, you cannot escape these things if you’re around a sandy area in California. They’re (confusingly) called Ice Plants. There are many different species that vary a tad in appearance and can be found in different areas around the globe, but the one predominantly found around my area is called Carpobrotus edulis. It is a perennial species with meaty, triangular leaves, and pink, yellow, or white flowers.

The pink flower variety.

The species is native to the coasts of South Africa, but it was introduced in the United States originally along coastal highways to stabilize blowing dunes. It grows quickly and expands into a dense mat covering a vast area in very little time, which is why it is considered an invasive species.

What’s interesting about it is that its optimal growing preferences are very well matched with most crabitat conditions. It thrives off of nutrient-lacking soil, so those of us crab enthusiasts with a sand substrate, this is the plant for you. I can’t say if it would be suitable for an eco-earth substrate, as I have only tried it in sand.

I must say, it thrives in my crabitat. The original cutting that I planted tripled in size in 2 weeks. The crabs seem to like climbing on it and balancing along the top of the leaves. They’ve snipped off a leaf or two but don’t seem interested in eating it.

If you’re wondering about toxicity – “Is it safe if my crabs eat it?” – you don’t have to look further than its name to find out. Carpobrotus is derived from the Greek, karpos, meaning “fruit”, and brotos, meaning “edible”. If you’re still not convinced, edulis, also means “edible”.

I’ve got crabs!

Yesterday, the tenants of the aquarium I showed you guys in my previous post have arrived in the mail. This species is not the most accessible and easy to find (no local pet stores in the surrounding metropolitan area carry them), and the company through which I ordered turned out to be run by dimwits, but I’m not going to get into this right now.

Without further ado, here are Lucas and Luna! They go by a myriad of names – Halloween crabs, moon crabs, purple crabs, harlequin crabs, etc. – but their Latin name is Gecarcinus Quadratus. They come mostly from Costa Rica, but can be found up and down the Pacific coast from Nicaragua all the way down to Panama. They are land crabs living in and around the mangroves by shore. Being nocturnal, they spend their days in burrows deep in the sand, and their nights foraging for food. Females go into the ocean periodically to lay their eggs, but only briefly before returning back to shore and the safety of their burrows.

Here they are, doing what I call the spider-man dance. You can see that his colors are so vibrant, while hers are more pastel.

A video of more spider-man dancing, which is actually a front for finding flaws a.k.a. escape points in the enclosure.

After that much clambering about, they quiet down and enjoy a piece of shrimp.

After a day of having them I’ve learned two things:

  1. Gloves are a must when handling them. (He seems a bit more tame, but she’s passionate about pinching fingers.)
  2. They love making burrows, and moving things around the enclosure, and knocking things down… Basically I have to deal with the fact that a neatly decorated tank is simply not possible with these two guys as resident bulldozers.

Rule #104: Goldfish bowls

Very well put. And for the record, you gotta love the ones with their “brains” on the outside too, can’t discriminate.

365 Rules of the new world

You know the kind I’m talking about.  The goldfish in a bowl has been one of the ‘first pet-experiences’ of choice for years. Just about everyone has had one. Unless, of course, your parents didn’t love you enough to get you one. OR… perhaps they had the foresight to know it wasn’t right.

I’m talking about those little bowls that are barely bigger than my beer glass. We throw a little gravel in the bottom and a plastic plant then stand back and say “yeah, that looks just like the ocean.” Then all that’s left is the goldfish to do endless donuts trying to figure out which way is out and pray for an early death; which will come soon enough. I mean, what better way to teach your kids about death. Even though goldfish can live up to 20 years, you certainly won’t have to wait that long…

Exciting news!

A house without an aquarium feels way too empty (even if it is a small studio filled with furniture to the brim). Sooo… I’ve decided to revive this blog.

I already got an aquarium.

fish tank, aquarium, terrarium

It was an awesome deal – FREE !!! Aren’t free things just the best?!? I mean if you had two identical candies, one which you got for free and the other that cost a few cents, wouldn’t the free one taste so much better than the other one? Well, in my world it would.

But I digress.

The tank came with a filter, heater, fish food, water dechlorinator, nets, and a bunch of other fish supplies. It also has a lid with a built in light.

For now it’s empty and my palms are so itchy to fill it. It will take me a couple of weeks to do this – getting the supplies, setting it up, and ordering the little “residents” that will call this tank home (can you guess what they’ll be?).

Stay tuned for more details.

MOVED – Book reviews

Midnight reading

In trying to keep this blog focused on small aquatic pets, I have created a separate blog which is dedicated to book reviews and reading related topics. I invite you to go check it out.

All is silent in the pond

DSC_4525In case anyone is wondering what is up with the lack of activity on this blog, here’s the Cliff’s Notes version: I’m all out of aquatic friends to blog about. Yes, that’s right, no more turtles, crabs, guppies, goldfish. Zero. Nada. Zilch.

For the benefit of keeping this post within reasonable limits, I’m not going to go into much detail. In the past couple of years, there have been a lot of changes in my life, big changes, the milestone-kind. I moved a few times which led to some downsizing in my aquariums, I’ve spent 2 months in Europe which meant leaving my fish in someone else’s care, and recently I’ve moved again, this time over 4,000 km away. We barely had room to breathe in a car stuffed full of things, so lugging aquariums was not an option.

I must admit, one of the things I miss is the routine of having an aquarium – the regular feedings, the water changes. Or just taking my eyes out of the computer for a few minutes every now and then and watch the fish’s elegant dance, listen to the filter’s soft murmur.

Getting an aquarium now is not a viable option until I know for sure that my situation is stable and I won’t be moving again in the foreseeable future. This is why things are going to be awfully slow around here for a while.

Goldfish – Car Enthusiasts

I had recently been informed that I am not providing all the items necessary for my goldfish’s optimal development.

Who knew that besides an aquarium, clean water, oxygen, food, and maybe some other fishmates to share all those things with, they have always dreamed of having a “set of wheels”. Well, colour me surprised! I guess I’d better get with the program, and soon.

Goldfish Picture Update

Hello world!

Here are a few recent pictures of my two adults. They’ve changed so much over the past 6 months, in size and colouring.

Enjoy!!
