Hi all,
I’m considered a newbie in the world of “shrimp-ing”. Just started this hobby about one year ago.
Anyway, the reason I wrote this is to share my experiences in shrimp rearing in nano cube without all those expensive gadgets.
In other words, shrimp rearing on a shoestring (though not exactly cheap :-P).

My tank config:
  • Tank (no brand) – 25cm (W) x 25cm (L) x 30cm (H) cube
  • Filter (no brand; capable of filtering 100liters tank) – Back hang-on filter (I will explain on the changes I did on the filtration media if needed)
  • Air pump (no brand) – single output air pump on NAG Aqua glass pipe micro air diffuser
  • CO2 – Compressed 1liter UP AQUA Aluminum with 40mm INTENSE PRECISION BAZOOKA atomizer (no drop checker; 1 bubble/6-7seconds)
  • Lighting – UP AQUA Z-series LED 30cm (L) Spectrum 8000K (on timer = 0700hrs – 1300hrs; 1900hrs – 0100hrs – 12 hours/day)


Substrate:
  • JBL AquaBasis Plus – about 4cm thick
  • JBL Manado – about 1cm thick


Water parameter (I use JBL EasyTest 6 in 1 – test strip)
  • GH – about 3 to 5
  • KH – about 2
  • pH – about 6.7 ~ 7.0
  • Temp – 26^C to 28^C (depending on ambient temperature)
  • Ammonia – should be zero
  • Nitrate and Nitrite – roughly 0.2ppm (using JBL nitrate and nitrite test kit)
  • TDS – 220 (TDS meter)
  • Water changes – 20% once a week


Water treatment:
  • Initial cycling stage: JBL Denitrol
  • Dechlorinator: Tetra AquaSafe


Others:
  • To increase pH and GH – Shirakura Mineral Powder
  • To increase GH – Epsom salt/Magnesium sulfate (cheap alternative :-))
  • mineral rock
  • Drift wood


Liquid fertilizer:
  • JBL Ferropol – 5ml once a week
  • JBL Ferropol 24 – once every day (discontinued after I gotten myself ADA)
  • ADA Green Brighty Special LIGHTS - once a day


Food:
  • JBL Novo Prawn
  • Gold
  • ADA Red Bee – finished


Flora:
Current:
  • Marimo balls
  • Subwassertang
  • Glosso
  • Limnobium laevigatum – floating plant


Previous:
  • UG – removed as it grew too fast, too furious. Now in emersed form

  • Staurogyne repens – removed as it grew taller than my tank ornaments. Not to mention 10cm long root system deep into the substrate :-S. now in emersed form
  • Xmas moss – removed as it started breaking off piece by piece. now in emersed form



Fauna (I don’t care if they interbreed :-P):
  1. Yellow shrimp
  2. Orange shrimp
  3. Red sakura shrimp
  4. Crystal red shrimp
  5. Red cherry shrimp
  6. Black bee shrimp
  7. Golden shrimp
  8. Red rili shrimp
  9. Yamato/Amano shrimp – kept in separate container as they are vicious and voracious

  10. Horned nerite snail
  11. Tracked nerite snail
  12. Malaysian trumpet snail


So here’s what I learnt after multiple shrimp deaths. ALOT OF DEAD SHRIMPS :-P :
  1. Do not rear Yamato/Amano shrimps together with your other shrimps. Contrary to popular belief, Yamato/Amano will kill and eat the shrimps while the poor shrimps are molting.
  2. On your air pump 24/7 to provide water surface agitation, hence soluble O2.
  3. Place sufficient foam (not too thick though) at the filter intake to avoid baby shrimps being sucked into the filter.
  4. On your fan 24/7 and place the air outlet diagonally instead of horizontal or vertical direction. I get 28^C in horizontal/vertical direction but 26^C when I place it diagonally due to bigger surface area.
  5. Limit the feeding to every other day. Shrimps are OK not being fed every day.
  6. Combination of Shirakura mineral powder (half mini stirrer spoon) and Epsom salt/magnesium sulfate (one mini stirrer spoon) diluted in 1.5 liter of treated tap water is more than enough to buffer the water and provide comfortable GH range.

  7. Use only de-chlorinated water to top-up those lost due to evaporation.
  8. Use Epsom + mineralized water to top-up after water change.
  9. Drip roughly 5ml of JBL Denitrol after every water change to rejuvenate the bacteria colony.


Let me know if this is helpful. I will post on the hang-on filter media setup if needed.

Attached are the photos of my humble nano tank.
