Mielo's 35lt Nano - Seahorse

Postby Mielo » Mon 02 Sep, 2019 4:06 pm

Hi all

Setup a little 35 liter Nano tank for my daughter.

System Objectives: Daughter to decide

Strike up Date: 30/08/2019

Display Tank: Aqua one Nano Reef 35...350 x 350 x 350

Display Lighting: Mariglow LED light unit

Stand: N/A

Hood: Glass lid

System Water: Natural salt water

Display Water circulation: Flow of the return pumps

Return Pump: 200L/hr pump

Skimmer: NanoSkim 40 Hang on Skimmer

Heaters: 1 x 55W heater

Evaporation Top Up: Manual

RO filtration: 4 stage reverse osmosis wall mount unit with an De-ionization post filter

Live Rock: approx 5kgs

Got some Live rock and live sand to seed the tank from my cousin's tank which has been running for over 8 years now. Saw at least two Brittle worms while aquascaping and there are heaps of copepods in the tank at the moment.

My daughter is very excited about getting a pair of seahorses for the tank. Now I have no experience where seahorses are concerned, so any advise is greatly appreciated.

Question: Should I even consider housing seahorses in such a small tank??

I suggest doing as much reading as you can.
It is many years since I kept a seahorse tank, and I'm not sure of the best references these days, but www.seahorse.org may be a good starting point.

35L seems a little on the small side to me, but it can probably be done.
Temperature control is likely to be your biggest issue. Even the tropical species like temperatures at the lower end.
Feeding and subsequent tank polution are also issues to be managed. Seahorses are slow eaters - they like to stalk. If you can train them to eat from a contained source it can help with removal of uneaten food. The biggest bristle worm population I've ever seen was in my seahorse tank where they bloomed due to uneaten seahorse food.

Not intending to put you off - just wanting to encourage you to go into it with your eyes open to avoid disappointment.

Regards,
Colin

This is exactly the kind of advise I am searching for Colin. Thank you!

I have been doing a bit of research and the issues that really stands out for me are: ensure the seahorses are captive bred, maintain pristine water quality, minimum flow in the tank, do not overfeed and must have passive/docile tank mates. The two species that are readily available here are the Kuda & Southern Knight, both of which grows to over 20cm in the wild that is and can potentially live for up to 9 years. If that is the case, I will happily upgrade the tank.

I am yet to find a supplier here in Australia that supplies dwarf seahorses.

Southern Knight seahorses are temperate, so really should be kept down below 20°C.
Kuda are a more tropical, so can cope with a little warmer, but probably still don't want to be much above 24°C.

Another species you may be able to find are Hippocampus barbouri - zebra snout seahorses, which are also likely to top out at 24°C.

There is a bit of information in the RTAW Reefpedia - although not comprehensive.

Thank you once again Colin!

I have read about the Zebra Stripe Seahorse, but its not appears its not readily available in New South Wales.

Pic of tank after initial setup

Three week into cycling and this appears on the glass. I inially thought it was hair algae, but on closer inspection, it looks more like a type of plant? It was all over my glass and I cleaned it all, abd its growing again.

Any ideas?

Why are my pictures appearing so bad/ blurry when I load it onto the website when it looks so clear on Photobucket? How do I remove the Photobucket logo on the pic?

Water parameters after third week of cycling:
Ammonia: 0.25
PH: 8.4
Nitrite: 0
Nitrate: 40
Specific Gravity: 1.026

The only parameter that is fluctuating is the Ammonia. Is that normal after the third week of cycling??

Photobucket are a pain in regards to hosting photos for linking. I suspect that the way to make them appear properly is to upgrade to a paid photobucket account.

Are there any other image hosting websites I could use to load pics on this forum if I do not want to upgrade my photobucket account?

Re: Mielo's 35lt Nano

The Nano tank is now approaching its fourth week of cycling. Algae is growing nicely and the live rock (approx 20kgs) and live sand is teaming with copepods. Will be introducing a colony of copepods in the back area of the tank where some of the media is by inserting small pieces of liverock. This could provide a steady supply in case the main tank is depleted of copepods.

My question is......Once all the parameters are settled, could I possibly look at introducing a mandarin as the first fish in the nano tank? There should be enough food (copepods) for the mandarin, but just worried about it being a newly cycled tank.

Any thoughts/opinions would be greatly appreciated.

Change of plans.... My little daughter has changed her mind and decided she wants a freshwater aquarium with a pair of Axolotls. Not sure why, but its her decision.

As a result my eldest son claimed the Nano and we moved it into his room yesterday. I took the opportunity to do a 30% water change with NSW. Will check the water parameters over the weekend and will hopefully be able to go shopping for his first fish. I don't think he is into seahorses as he wants active fish, so we will have to revisit the tank inhabitants for the Nano.

I am experiencing lots of issues loading pics, so I gave up.

Water parameters after fourth week of cycling:
Ammonia: 0.50
PH: 8.4
Nitrite: 0
Nitrate: 20
Specific Gravity: 1.026

I am getting a bit confused about this cycle. The Ammonia just fluctuates between 0.25 and 0.50. Could the ammonia levels increased due to moving the tank earlier in the week? I was planning on introducing a green chromis on the weekend but decided against it due to the ammonia levels. At least the Nitrates dropped.

Should I just be more patient with the cycling of the tank or is there something more sinister going on?

The fact that you have measureable ammonia suggests to me that you still have organisms dying off or organic matter decompposing.
I wouldn't be adding fish at this stage.
It's one of the most famous addages in our hobby, but nothing good happens quickly in a marine tank.
"Cycling" a tank is more than just establishing the nitrogen cycle (which you can measure via ammonia / nitrite / nitrate testing.
There are untold other equilibria and biological balances that need to establish themselves, most of which we are oblivious to.
The process takes the order of weeks and months, not days.

Check out the sticky threads at the top of the New to the Hobby forum, especially this one.
An excellent read which gives an idea of what is happening in a newly set up tank.

Thanks Colin. Will keep monitoring the parameters and be patient.

My tank just exploded with tiny moving white dots on all the glass panels inside the tank. Based on research, I believe its copepods/amphipods breeding in the tank?

The Ammonia test results API test kit continually gave me a reading of 0.25, so I decided to take a sample of my water to a pet store to check it. All my parameters are perfect.....guess I will have to go and purchase a more reliable Ammonia test kit. I introduced 4 hermit crabs and they re having a ball.

Tank is currently overrun with pods and I have them in the back built in sump of the Nano in some liverock rubble as well. Will probably go and purchase a Green Mandarin this weekend to keep the pod population in check.

Introduced the following to the tank thus far:
2 x ricordias
5 x mushrooms
4 x small hermit crabs
1 x 5cm mandarinfish

Everything seems to going well. The mandarinfish is just swimming and pecking everywhere and seems to be enjoying all the pods in the tank.

Next on the list will most probably be:
a pygmy angel
Firefish
Royal Gramma

Zoas
Hammer coral
Green star polyps
