My 4G Mantis Pico Tank Journey

Recommended Posts

Just wanna share my experiment using 18L Ocean Free tank adapting for marine purpose. 30Lx18Wx20H. Good footprint on top of my washing machine which is the only place my wife allows for marine tank now.

Basic setup when bought comes with underpowered undergravel 3V filter and top drip down filter. Flowrate is unknown but extremely slow. Comes with 10 white LEDs of unknown wattage and wavelength and 2 moonlight LEDs again of unknown power. Comes with hood (anti-condensation) and 3 plugs. See picture below for tank during cycling on 4th Feb.

Cycle done with some live sand, live rock and water from my existing RSM plus an addition of dead gravel and coral chips to 5cm depth.

Very short cycle registered.

Put in a Hailea internal filter with foam and carbon at 380l/hr flow to augment the flowrate.

Highest spike on 3rd day at Ammonia 0.5ppm, nitrite 0.2ppm, nitrate 5ppm. On day 7, ammonia 0ppm, nitrite 0.05ppm, nitrate 2.5-5ppm. pH: 8.2, salinity 1.022, temp: 30.

Did 30% water change with nsw before coral stocking.

Put in some xenia, mushroom and aiptasia and FTS below:

Main problem is temperature control which rise to 31.5 even at night with slight open hood. Now resorting to fan to bring it down to 28 as below. Blu tack to mark water level to top up distilled water.

Need experts here to advice on cooling the system as chiller is out of question.

Nice species tank!!!

What food do u give it??

I used to have one peacock mantis many years back.

I've been giving her frozen market prawn which she likes. Likes food to move around before taking.

Tried mysis shrimp, garoupa slice and hikari crab pellet. Surprisingly she also take them but seems reluctant to eat. She took some MLS pellet this morning. Getting her to be pellet trained so that i can do short travel.

Interestingly, she'll store any unconsumed food by digging a deeper burrow and packing it at the side of her main burrow. She also deshell and leave the shell at the front of the burrow.

Thanks to the advice here, I got a dymax cooler fan and now the temp is at 26-28.

you make me very tempted to make one mantis tank too...

i almost got myself a mantis at cf.. they were constantly hitting on the breeder box and their eyes follow u as you move.. so evil,

your nick does signify why u kept it though!

do update often .. if all goes well for u i shall make one as well to house these violent kids

Brown SPS > Kinder Surprise

White SPS = Kinder Surprise after expiry date

Assumption killed the dinosaurs, they didnt have test kits.

Just a brief of what happened to my mantis pico... xenia was doing badly and addition of iodide and 50% water change improved things significantly... developed new polyps but not opening as much.

Added florida ricordia but the epoxy clouded the water... try to attach but ricordia keep migrating down...

Mantis shrimp move house to underneath the bigger rock and the ricordia landed right at her entrance.. peace and quiet for one day.... the ricoridia seems to be expanding and the flourescent green is looking great.

This morning...... ricordia is gone :eyeblur: ... slime all over the tank and the pebbles it was on is inside the mantis lair when i lifted the rock.... the mantis is still smacking the remains on the pebbles. Expensive meal :angry2: and water quality is crap.

Anyone heard of mantis eating ricordia? I tot ricordia has no natural predator.

Don't think it ate it.. the pebble is just in its way so probably using it as its home decor.. BTW they can melt off very fast if its dropped face down on the sandbed.. Thats what happened to one of my Yuma.. came back after work and its gone.

Why do we use "My 2 cents worth" when 1 cents are not legal tender in Singapore anymore? Shouldn't it be 5 cents worth?

bro pico i dont recommend dosing A+B, might be too strong even if its alittle.

ok thank for advise... btw can dose iodide, pH buffer or Ca then? Or just change water? worried iodide not enuff for mantis moult and Ca not enuff. Also my pH at 8.0. not great as well.

now nitrate down to 5-10ppm but not ideal. xenia melted. 2nd casualty of my pico experiment after ricordea. any suggestion how to bring down further? My macroalgae on live rock dun seems to be helping.

Thinking of adding leather frag from my other tank but heard that it produce slime which inhibit other corals. any opinion?

My ph recently 7.8 Nia coz of the constant topping up of di water so I do dose ph puffer as it's not strong. I tried dosing ca and A&B before but I think it didn't produce very gd result. Seen my hermit molt few times Liao. I recommend u start dosing with ph buffer 1st ok? Hardy corals shd be alright even with little dosing.check yr saltmix oso. Maybe some coral additives will do too

PH

PH fluctuate throughout the day. early in the morning, it is lower.

after you lights are switched on, it will rise by 0.1 or 0.2

If you would like to increase, you can add some PH buffer, Kent marine pro-dkh.

but I think 8.0 is ok really. What water are you topping up with? If you are using tap water + water conditioner, you should be quite ok cause tap water has quite high PH.

nitrate

10ppm is ok. dun have to lower. If really want, do more frequest WC.

Eqpt: Deltec MCE 600, Tunze 6055 with Tunze 7091 controller, Artica 1/15 HP chiller, AquaIllumination Sol Blue LED Light System
