I just noticed a macro algae growing on one of the rock faces, it's flat when you view it from the side, and had a oval shaped end that's blue under the light. I wonder what it is, going t have to look it up. Any ideas?

Need a cleanup crew too. How many snails/hermit do you guys usually use in a tank of this size (34 litres, or 10g)?

The cooler arrived today! Here's some photos, now I just need to figure out if I need to put a resistor on the fan's power, or is the little thing on the side already a resistor?




The 8cm fan I wired up with a 12V DC 300mA PSU. I used a little plastic nut to protect the wire joint. Each wire is insulated by hot glue.

The quick release made from velcro cable ties.

OK, anyone know what kind of (macro)algae this is? Their tips are blue. Bad or good?

Louis, I have 3 turbos, 1 trochus, 1 orange striped hermit and 1 decorator urchin in my 12G. They are a great clean up crew - especially now that I finally seem to have my nitrates under control (thanks to purigen).

cute cooler!

I have potentially very bad news! I flickon the light, and there it was! an Isopod! it swam aroud then dug itself under a rock and disappeared.

Reading on RC, I can say its exterior anatomy is that of a Cirolanid Isopod, I can only hope it is a scavanging variety and not a parasitic one. I would hate to nuke the tank and restart, since treating this bug is very difficult.

However, I might leave the tank fishless for maybe 3 month and see what happens, my original plan was for an invert tank anyway.

Anyhow, the live rocks were from Auburn Aquarium, so avoid their LR for a while (make that a LOOOOONG while) since for anyone who wishes to have fish, parasitic isopods are the pods from hell :furious: :furious:

Here's an article from Reef Keeping Mag that's good reading:

mmm sounds like something to do at night, grab a torch and a net. i also hope that its a scavenging variety.

good luck with the hunting

The little guy is a great swimmer and digger, I doubt I can catch him with a net. Apparently they are nocternal, and detach from their host when light comes on, and they come out of hiding when the lights go off again, therefore some people never realise they have these bugs.

I am quite p***ed off about this because the tank just entered the nitrite/nitrate cycling stage, and I been waiting to add a cleanup crew!

On the up side though, the rocks came with an awesome hitchhiker! I believe it's a coral from the Siderastrea genus of the Order of Scleractinia. These corals are rarely collected because of difficulties in removing them from their attached rock. Mine is an orangy pink color and around 8cm in diameter. These corals are known to tolerate extreme conditions and dubbed "almost invincible". Mine has tolerated through cycling conditions with ammonia conc greater than 1.6mg/L, nitrite of 1.6mg/L and nitrate >110mg/L. This little guy came to me totally bleached and recovered to full glory in less than a month!

Oh I get it! You guys are not replying to my thread because you are applying peer pressure and see if I would hurry up an get some corals! :devil: :pirate:

Well corals you want? Coral you shall have! Allow me to present you Siderastrea sp.!! Came as a hitchhiker on the LR and survive through chemical hell only to come back in full glory as a testiment to its invincibility.

Sorry I lied, they are not all corals :wavey: You tell me what this is?!

The tri-tunicate, hopefully it hasn't been ID'ed, then I can publish a paper on it :roflmao:

Is it just me, or have you guys and girls also noticed that I tend to take photos of the strangest things in my tank? Who would have known a tank of LR is so much fun?!

the live rock when you 1st get it is the most interesting, then all the little critters either die, fall off or grow up and are no longer cute ir interesting - mine's recovering from cyano so is very very boring now. Love your pics :clap:

Hey thanks for the compliment regarding my photos!

Well, today's been a very expensive day. This is what I acquired:
1x male Green Mandarin Synchiropus Pictures
1x Hermit crab
1x Turbo snail (currently going to town with the algae, at this rate, I expect to see non when I wake up tomorrow :bow: )
1x Astrea snail
1x Gorgonia with fluro green Goniopora next to it.

I also got a pack of Hikari frozen food for the mandarin, which will also be fed to the other corals. The mandarin is already on frozen, and eating very well
:thumbsup: Right now he's hanging out at the back corner where there's algae on the glass (this is where pods hang out too), clever little guy!

Photos will follow tonight!

The tank has finally cycled! I added 1 turbo, 1 astrea and 1 hermit. The snails have since mowed through the algae like there's no tomorrow, in fact I am almost worried that they will starve in the long run?! Now they are taking a break, must be too full!

Wiring the peltier cooler: The peltier draws 60W of power @ 12DV, which means it will need a power supply that's capable of 5A of power. I got a PSU that's designed for car and personal coolers that meets that rating. In reality, the peltier draws 4A, and the fan draws 350mA, so I am still within spec.

The black object on the side of the heatsink is a thermal cutout that will turn the peltier off in case the fan fails.







Goniopora that came with the Gorgonia. They are both sitting on a piece of large tunicate! I feed these guys the Hikari brime shrimps.

Last but not least, welcome the new resident of nanoville! He's a male Synchiropus Pictures that's on frozen food already. I am working on traning him to eat sinking pallets too. Wish me luck!

Cooling capability:
Time - Tank temp - fan/peltier on? - ambient temp - light on?
12:08PM - 28.5 - both ON - 29.0 - light OFF
12:50PM - 28.0 - both ON - 29.0 - light ON
13:20PM - 28.5 - both ON - 30.5 - light ON

14:00PM - 29.0 - both ON - 31.5 - light ON
15:35PM - 30.0 - both ON - 32.0 - light ON
16:52PM - 30.0 - both ON - 32.0 - light ON

hi Louis

im looking at your tank temps. seem its only pulling it down by 2deg.

im looking at these probes and was sort of hoping it would pull it down but at least 6 deg ( i want to keep my 2x2 octagonal at 24deg) the octagonal will have a overflow and a small sump in the base ( where the probe will be).

also noticed that in your pic the entire probe isnt submerged beneath the water.

how are you tank temps looking now.

cheers aron.

these units would only be most effective on a small 30L Tank.. anything larger means that it will have very little effect on pulling down the temperature.

the tank is looking great! i love how simple a nano is.

Hey Aron,
That's preciously why I "data logged" the cooling capability and posted it here. The IceProbe is really only useful for counteracting temperature generated by equipment, and especially useful when your fan is already doing everything it can but you still need that 1 extra degree of pull down.

Yes, there's still about 1.5cm above the water level, but since the probe is made of conductive material, I figured it wouldn't matter too much.

My tank temp is under control, I will be leaving the lights off on the hottest days, since the tank still receives natural sunlight, it will just be a cloudy day for nanosphere :D Now my only issue is that the temp sensor on the heater is rather crappy, I set it at 27, it doesn't kick in until around 26, then heats the tank to 28... made in china, what can I say?

Well on the way to a fantastic nano!

For some added movement, what about a red line cleaner or a blood cleaner (or a pair of either)

Fantastic mods, and fantastic photos.

what if you had a couple running.

Thanks Jamie! I would love one/pair of red line cleaner shrimp, but I just can't justify the cost at $105ea!!

I want sexy shrimps, but the one I saw before was sold unforuantely. However, I need some flubber first for them to hang out on :)

I am going to avoid BTA for now, I saw one moving across a display tank with a motion that can only be described as "running". Quite incredible actually.

Aron, a couple of IceProbes would cost around the same as a nice little chiller such as the AquaMedic Titan (around $520 each), which would be less hassle in my opinion.

Since my tank is small, I want to stock it with facinating organisms, and perhaps stick to just one fish. It's quite frustrating feeding this little guy at times, he sit there looking at the food float pass him... bah

I am going to buy the biggest and smallest sized Golden Pearls, for the Mandarin and the Gorgonia. Somone on RC claims he's had great luck using GP to feed his mandarin.

Let us know how the gorgonian goes. Hope you can keep up with the feeding.

Heres a thought, if youre gonna be feeding so much, and you dont mind your nitrates going up; why not do a tank filled with non photosynthetic corals like tubastreas, dendroneptheas (sp?), gorgonians etc. I think thatd look great.

But then again, itd be a bit of a waste cos youve already got a halide.

PS, how much are sexy shrimp selling for there?

That is an interesting idea, to be honest, I got the MH for the photography :P well I was thinking of SPS too.

I saw the sexy shrimps for $25 each... they are high on my shopping list.

Some update:
I have stocked the tank with these corals this weekend:
1x Sinulria sp.
1x green+orange zooanthid
1x orange Dendronephthya
1x corallimorphian (came attached to the zoos)

The Dendronephthya will be fed the 5-50micron golden pearls with other mixture of food much like the Gorgonia.

In addition, the litle Mandarin is now feeding with earnest! I add garlic to his frozen food and he loves it! Now I know how parents feel when their skinny kid is eating! :)

I have also done a quick rearrangement of the rocks to provide more estate for corals.

Lastly, I have wired up a cold cathod for a moonlight, this allows me to see what no good my hermit gets up to during the night. The snail ate the beautiful red macro algae that came with the dendro, I was quite upset with him!

Pics to follow, I didn't get a chance to get photos last night before the lights went out, since I am rather reluctant to switch the light back on after it's off.

Great pics

Wow, that 700 mega pixel camera sure makes the tank look good :roflmao:

Really nice tank, are you gonna turn it into a high nitrate tank with lotsa non photosynthetic corals?

Also, seeing your dendro makes me wanna get one if i can keep it alive. Its nice you got such a small sized one. I see lotsa nice sized (30cm expanded, at least) ones at LFS here.

Has it started eating yet? Ive kept hitchiking ones close to the gravel where they feed off the detritus ive stirred up periodically (near stagnant growth though i get lotsa new small colonies).

That is tempting, but can I withstand the criticisms from the Dendro/Gorgonia Police? Kidding aside, I am giving that a thought.

This Dendro is around 15cm tall when fully expanded, and he does go through a few cycles of deflating/inflating during the day. According to the literatures, this is to facilitate gas and waste exchange. I got him for a decent $45. Anyhow, I am quite determined to keep them healthy and thriving. Whatever it takes really.

Mine has full polyp extension, sometimes even when it's deflated. this thread on RC is the Dendro study group where people are sharing their experiences with this coral.

Havent had the time to read the whole thread on RC but have looked through the first page. I think that stirring up the detritus in the sand would work well though.

Itd be really sweet having a non photosynthetic tank (although, as mentioned, a bit of a waste of 150w halide). I dont think anyone on this forum has one quite like it. And besides, you cant go half dendro, half sps.

Is 45 decent for a small dendro? Ive seen giant ones for about $59 so i dunno, never having seen any small ones.

Id SO steal the idea for a non photosynthetic tank but im still set on a pair of clowns in my 18" cube. Itd be cool if i could have an anemone on one end and a cave filled with pretty colours on the other end.

Lastly, does the dendro really eat the oyster eggs?

For the algae you wanted an ID for try Dictoyta sp usually branched /forked and often a blue colour. Some say its bad but I have never had dramas with it and have small colonies thriving in my tank. Its never gotten out of hand and is quite nice looking for an algae.

Cheers Andrew

Infidel: Hmm I feel so weird addressing you with that! It will be sweeet having a coral predator tank. Let me sit on it for a little and do a few more days of research, then I will give you guys a more accurate ans! I am not sure if 45 is a decent price, it just seems ok. I might get a Tubastrea if I can find a small colony, all the ones I have seen so far are quite huge.

The guys on RC seems to having good luck with it. Today, I meshed up some brime shrimp (Hikari) that has phyto added, and target fed the Dendro. It seems quite happy to catch the particles!

Andrew, thanks heaps for the heads up, no one across 4 forums could ID it until now! The snails likes to rip it off the rocks. Currently it isn't running wild, I am more concerned about the green algae on the glass!
