    Default Cardinals Sulawesi shrimp at pH 7.0?

    Hey guys , I'm new to these beautiful shrimps and just got some of those few days ago . The shrimps are doing fine until now , but since my pH got a bit low , i just wonder wether they reproduce well in the future . It seems all breeders here have their tank pH ~ 8

    My water parameters :

    pH : 7.0
    TDS : 220 ( not sure if low or high )
    Temp : 28-29C

    Hi Kloudie,

    pH does not matter too much, as long as it is not acidic. TDS does not matter too much as well, it does not tell you exactly individual mineral level.

    What salt are you using to replenish the RO? Can you let us know more details on your setup, such as the substrate, filter, feeding regime and water change regime? Let me know and I can advise you further.

    By the way, how long have you been keeping them?

    Hi hyoushoku , thank you for your answer

    Im using Sulawesi Mineral 7.5 , the set up is :
    _ 80x40x40 tank ( about ~ 100L )
    _ The substrate is Project soil 7.2
    _ Filter : Eheim Substrat and 3 sponge filter
    _ Feeding : once per 2 days , with little amount . The food is the mixture of spirulina and some brand products , all are grinded.
    _Water change : : 15% per week

    Im only keeping them for nearly 1 month , and the pregnanted shrimp from the old owner start to give babies . The babies is kinda active and healthy , too

    Hi Kloudie,

    A few things to take note:
    1. Feeding once every two days may not be enough. Not sure your shrimp is true captivity raised, for wild or a couple generation captive raised shrimps tend to graise on powdered food and algae around their hiding place. For my case, I feed them twice a day with tiny amount.
    2. Make sure you have plenty of soft algae around their hiding place.
    3. They need a lot of mineral via their diet and water column. Once your substrate depleted, they will starting to die one by one. By then, you will need to feed them mineral powder and add trace fert to the water.
    4. Prepare the RO+salt at least a day in advance and use a air pump it power head to dissolve the salts. The salt shrimp salt is carbonate-base and new water can have pH as high as 9+.
    5. Change 10% water instead of 15 if possible.

    Hyoushoku, what type of salts/mineral you think are essential to them?

    congrats on your new shrimps i would use minerals to but here in denmark they been breed in tapwater ph around 7-7,5 and 200ms.

    hyoushoku-san how goes whit your shrimps

    Hi Guppies,

    As I'm relatively new to Sulawesi shrimp (about 5 months plus), I have not full study these shrimps. Given said that, I applied the same knowledge of keeping soft water plus what I studied from all the geologist reports about Sulawesi lake systems, I managed to keep both Cardinal and Harlequin shrimps successful at first attempt.

    In summary, I find that there are only differences in keeping Sulawesi shrimps and soft water shrimps. Other then those obvious differences, which is pH and temperature, they are the:
    1. Rich mineral substrate / daily dosage of slow dissolving minerals to supplement their diet.
    2. Higher trace mineral dosage into the water column. The alkaline water causes transitional metal-based mineral to be lost very fast.
    3. Need a lot of fresh algae in their hiding place.

    If you ask me what type of minerals are essential, it will be exactly the same as soft water shrimps (check my blog for the mineral list). All minerals are essential to living organism, thus there should be no differences among species. However, the availability level of some minerals will elevate the color better, which I discovered with soft water shrimp. For Sulawesi shrimp, I have not figure out this aspect yet. I am very busy with my work this year, hopefully I will have time to experiment this soon.

    P.S.: When I mentioned mineral, it does not mean only cation. Anions, such as sulphate, phosphate, chloride and molybdate, are crucial to shrimp's health.

    Can you give me a link to your blog? if it is not allowed please pm me.

    I've never paid attention to mineral depletion over time, this was probably why although i could keep harlequins alive, I failed to keep their babies survived.
