I assumed it was just the vodka you were dosing - not the tank, but yourself

Have you actually touched the HeΙΙfire Anemone? Does it sting through gloves?

I've heard that garden eels are notoriously difficult to keep - but they sure look fun.

Paul, your mandarins are looking fat and happy. Do you feed them specifically, or leave them to just pick around in the tank?

The eighteen-fifties? But seriously, I do think you're right about some of this, and I think some of these theories are catching up to the industry. I notice that WAMAS sponsor LRS specifically supplement their frozen food with bacteria, and I keep hearing about major success stories in getting fish to breed and getting their offspring to survive using this sort of food.

Whew! What a month! The tank has just exploded with awesome stuff. The caulerpa I got from BRK has just been going nuts in the tank. I have to take out a handful every two weeks or it starts to grow a large chunk at the top and shade everything. I picked up a rock from a tank teardown of a friend of mine; my rockwork just seemed "bare" and like it was missing something. It's a pretty good-sized rock with a bunch of anthelia and yellow sponge in it, along with mini brittle stars which I had in my 72g bowfront but was missing from my last tank. I also have also seen a massive amount of copepod colony growth - it really is so much easier to "long cycle" a tank without fish and let critters like this get established before introducing predators. This is the first tank I've had with the harmless "wheel hydroids" (dots on the glass), which have been interesting. I've scraped a few out and have observed them under a microscope. They seem to resemble the infant jellyfish stage that Jon talked about at the last meeting. The tank has been cycling for six weeks now and things have definitely settled down, so I introduced my first livestock - a pair of aquacultured clowns that we picked up from BRK over the weekend. Johnny was patient and let my four-year-old pick exactly the pair she wanted. Next livestock acquisition will probably be an ORA yellow assessor - I'm hoping someone locally is an ORA retailer. I'd like to keep all-aquacultured fish in this setup if possible; not only do I think there's less chance for disease that way, but as a capitalist at heart, I want to send the message with my wallet that I value efforts to breed species for hobbyist use rather than catching them wild, even if it's more expensive; after all, in a hobby where you pay $10/lb for rock, why is there any hand-wringing at all over 10-15 additional dollars a fish to support sustainable aquaculture?

If it's already dry and relatively clean, I'd just do a vinegar soak vs. bleach.

I couldn't even deal with aggressive cinnamon clowns, let alone that.

Rob is way more knowledgeable than I, but I would also avoid having rocks close to the glass because of how annoying it is to clean! I now place rock far enough away that my mag-float can pass unimpeded on any surface that will grow visible algae, and it makes a big difference in the "day to day" look of the tank.

Realized I hadn't posted any photos in a while of this! One of my jellies was acting a little off when I first got him, and a day or two later started "hula hooping" - where instead of one coordinated "pulse" where the jellyfish moves itself, it instead will sort of twitch one quarter of its body, then the next, then the next where it looks like it's, well, using a hula hoop. Unfortunately, this is indicative of nerve damage in the jelly, but fortunately, as Jon mentioned, jellies can pretty much regenerate anything, and the impacted jelly is already back to normal albeit noticeably smaller than the other two. Some of the "dots" you see in their tentacles are the baby brine shrimp I feed them. I have skipped the included powdered food almost entirely and feed exclusively baby brine shrimp. I think it ends up being better for the tank, as there's functionally no uneaten food; the jellies are surprisingly good at capturing all the brine shrimp within 20 minutes or so. My usual routine is to make baby brine shrimp over the weekend and one batch tends to last my jellies for the week. I am probably going to try adding some copepods from my main tank into their diet a couple times a week. Water quality is a big deal with jellies because they can't handle any ammonia and the water volume in these tanks is pretty small. Additionally, bio filtration is limited, so to be on the safe side I end up doing water changes several times a week - I just scoop a cup of water out of the front and dump a cup of saltwater in the back. A water change takes me less than a minute. I have a bunch of pre-mixed water sitting in a large container so the water I'm adding is the same SG. Also, as mentioned before, there's really no evaporation to speak of, so no ATO and no need for freshwater. I haven't had any algae growth and my ammonia is at complete zero and I experience minimal nitrate. I also added some Seachem Matrix in the back to add to the biological filtration.

Do jellyfish like clown fry, I wonder?

Expired :(

I struggle with this too, and am not sure where the balance is. On the one hand, the more I keep my tank "controlled", the less risk I have of bringing in unwanted algae or pests. On the other hand, on its face, a certain amount of biodiversity seems good, and I really like those little saltwater tube worms that pop up. The more I think about aquarium bio-diversity though, the more I suspect Rob is right - if you bring something in from the ocean, it's going to have a lot of diversity, but a lot of that will probably die off (read: spike my nitrates) in a closed system that doesn't have the food chains and environment of the ocean. As for paul b's aquarium, if he keeps it going a couple more decades, his fish will evolve legs and he'll have to turn it into a terrarium.

This is definitely a Paul B question. He uses ocean water in his 40-year-old reef tank and swears by it.

They're here! One of the benefits of the WAMAS deal was that JellyfishArt sends the jellies overnight free - it is two-day shipping normally. I'm glad they did this because I would have felt nervous with the jellies being in transit for two days during my first experience with them. The bag water was about 1.026, whereas my tank was about 1.022, so the jellies sunk even after acclimating them for an hour. I raised the tank salinity to 1.023 and that made them perk up a bit. If I had to do it again, I'd mix the water a bit saltier and have some on standby to get it closer to what the bag water ended up being. The company recommends 1.020-1.023, so I'm going to bring the salinity down gradually over the next month. After about 2 hours, the jellies were no longer at the bottom and were floating around. I had some baby brine shrimp going in the hatchery and they immediately perked up for that.

In other news, I added several scoops of SeaChem Matrix in the back for additional bio filtration, as well as a mini-bag of Purigen for additional filtration in addition to the little chemi-pure blue nano packet they include. To Jon's credit, I have had zero water lost to evaporation per his claim in the two weeks mine has been set up. I will definitely be able to handle what little evaporation does occur by mixing it slightly fresher in my water change accordingly. Hacking of the base of my jelly tank has taken a back seat as I've been writing all new code for my Reef Angel and getting their RF module to properly control the Radion the way I want.

Paul, Did you see this occurring in any US-based operation? I have this this level of carelessness (and also using toxins to stun fish) in SE Asia, but had not heard of this happening in US waters.

Well, today should have been the day to order the jellies - but I noticed that the temperature is going to get down to the thirties tonight, so I'm putting it off for a day or two until it warms up. I actually called Jellyfish Art and they put me through to our esteemed WAMAS speaker Jon (DrReef on WAMAS) to answer my question without me even asking to speak to him, which was impressive.

Hey Sean! I miss coming by your place - you always gave me the best deals on big boxes of salt. I tried to drive by after I got back into the states and was sad to see you had moved on. Hope things are well!

Progress made! My rock has been sitting in a sealed mixture of water and bleach for the last two years while I've been overseas. In retrospect, this was a bit overkill. I've done a lot of rinsing of the rock and it's still clouded the water a bit. I picked up some algae from BRK a couple days ago and have started the cycle. I'm loving the Tunze 9004 DC skimmer. This thing is a workhorse. It's already way better than the IM skimmer that I had on this tank the last time around. I'm currently having to empty the cup three times a day. It has done pretty good at removing the cloudiness of the water.

I will definitely take you up on the offer when my tank is a little more mature. They look fantastic!

A clownfish in five gallons is probably not optimal. LiveAquaria recommends one 600% bigger than that. I could see maybe a twenty, but a five is going to feel like living in a porta-potty in both living size and environment quality after a few weeks.

My jellyfish tank arrived yesterday! My wife is really excited - enough so that I get to put this tank in the kitchen/breakfast room area! Unfortunately, I'll have to wait until the end of today to start the cycle because we're getting new countertops installed. When I saw it at the meeting, my first thought was how I could modify it to make it better, because that's just how reefers are, right? Filtration I'm probably going to add a small amount of porous reef rubble or something in the back to cultivate additional bacterial denitrification. I notice that Jellyfish Art has "marbles" in their bigger tanks which probably aim to do the same thing. Electronics The light is "okay" - but I want the functionality Jon mentioned the new one will be coming out with, like the ability to have multiple lights that sync to music. Fortunately, it will be really easy to add this functionality. The base is mostly hollow and lighting is provided by this light here: It plugs in to a simple two-prong socket in the base, which can be easily removed. I am considering a black piece of cardboard or plastic to put in the base vertically and divide it into a left/right portion so I can have two different LED colors. So now I'm thinking of cool stuff that could go in the base, and initially considered a Raspberry Pi Zero W with two LEDs on it that would give me a left/right LED channel plus Wifi/Bluetooth and some semblance of an operating system so I could have a predefined schedule plus control it with my phone. Bruleyii mentioned this neat Arduino device which is pretty neat. AlanM already did a neat LED board with an Arduino gemma that I'm going to also look at as an implementation option.

With a five gallon tank, I think you'd struggle to comfortably fit anything bigger than one of the tiny gobies like the yellow clown or neon blue. Fortunately, both are relatively easy to care for. If you seed with rock from your tank, I'd still give it a week or two of watching paramenters with the sand - which, if you're going to insist on putting in there, I'd go aragonite before synthetic. If you go bare-bottom, you might have an easier time cleaning with a pipette or turkey baster, which is all the more critical for a water volume that small.

Those mushrooms are pretty cool. I'm not sure I've seen anything quite like them - like nearly-ricordea-but-not-quite. Where'd you pick them up?
