#TinyTankChallenge Ethan Update #2

As of yesterday, my tiny tank has been up for a week. So far, no losses, and I think I may have avoided a major cycle by using material from my big tank. I’m planning on checking my levels later today, and I still want to give it some more time before adding the more delicate stuff like the sexy shrimp.


Cuttlefish Update

So I woke up, checked the tank, and found eggs this morning. I count at least 3 but they’re all tucked away in the back, so it’s hard to see. There may be more. She’s not quite 5 months old, but I noticed one of the 4 acting differently this week; much more shy than usual, and then actually observed what looked like mating, so clearly I was wrong about having all males.  

#TinyTankChallenge — Ethan Update #1

I decided to take a calculated risk today. Since I used substrate, water and rock from an already established tank, and I’ll be doing frequent large water changes weekly, I decided to just go ahead and add a few TINY frags from my big tank. If I have a big ammonia spike I may lose them, but everything I keep is pretty hardy and has already endured some of my stupid mistakes.


A snail hitchhiker. Those zoas opened up about ten minutes after being introduced to the tiny tank. There’s some bubble algae in there, but hey, nobody’s perfect.


Also, speaking of hitchhikers, I have no idea what these tentacles belong to, but it came in on that rock and I’ve never seen it before. Some kind of anemone maybe?




Hey guys! My #tinytankchallenge project is going to be a 2.5 gallon “pico reef” tank. I haven’t completely decided on what I’m stocking it with yet (probably some zoas and frags from my big tank which won’t cost me anything), but I just ordered most of my equipment, so I thought I’d get things rolling with that.


I had a $50 Amazon gift card from my birthday, so I’ve technically only spent ~$40, however, for fairness sake, total so far is $68.48 US dollars. I didn’t need to buy a lid, since the tank came with one, nor substrate, since I already had a bag of crushed coral lying around. (I’m not counting that anyway, because lots of people like bare-bottomed reef tanks, so this was optional). CXehKVeUAAA0usSI also have a small powerhead handy I may use, depending on how powerful that little filter is. For live rock (which will be doing most of my filtering, I have a bunch of small chunks I can scavenge from the big tank, but I may buy one nice piece from the local shop, which will probably put me right at the $100 mark.

I went with the 25 watt heater, even though it’s about 3X what I actually need because I’ve had good luck with that brand and didn’t want to chance an off-brand, pre-set betta heater, which is basically what all 10 watt aquarium heaters are. Funny, probably a better chance of cooking your tank with one of those than a decent thermostat controlled heater at a higher wattage.

I chose the filter I did because of the thin build. A lot of people use Aquaclear filters because they add the most water volume, but they’re significantly more expensive, around $40 or $50 and I’m really just using it for some chaeto algae. The reviews on this filter were generally good (quiet) and since it’s going on a desk in an office, I liked that the pump was internal and the external case is one solid piece so there’s no chance of a leak. I may have to mod the pump to slow it down by removing one or two of the impeller blades.

There really isn’t room for a fish in this tank, besides maybe a small goby, but I’ll probably have some micro-brittle stars, snails and such. Maybe an emerald crab.

Cuttlefish Updates

Sorry for the lack of posts recently. There hadn’t been much to report, since basically everything was proceeding well: Cuttles were eating, including frozen foods and steadily growing. However, this weekend, after consulting with some other cephalopod keepers I decided it was time to release the krakens into the main display tank. So far, everyone is doing well. They prefer to hide when the lights are on and it’s very difficult to spot them as they’re only about 1.5 inches long. But when the lights go out, they’re very comfortable prowling around at the front of the tank.

Before I let them out, last week, I managed to capture a video of Laz grabbing a shore shrimp:

1 Month Cuttleversary

Saturday marked 1 month of having these little guys. It’s amazing how much they’ve grown. The largest of the bunch, Rorschach is now almost an inch long, and is happily eating 1″ shore shrimp. I made the decision this weekend to put Rorschach and Lazarus in a separate net breeder of their own to make sure they weren’t over-dominating the smaller two at feeding time.
Jury is still out on eating frozen. I’m wondering if it really only worked before because I added a good number of live mysids with the frozen and they sort of lunged at anything and everything out of confusion. They seem much less interested now, but I’m continuing to offer it at every other feeding.
