Lowkeys B18 Power Protein


Recommended Posts

I have been trailing this product for about 8 months now:

Ingredients: Lactic acid bacteria, crustaceans calcium, reduced maltose, mulberry powder, yeast


I cannot argue with the fact that it increases my berried ratio among females after feeding. I sceptically attributed it to the protein component only initially, but trialling one tank on protein- high Ebita Breed Hinomaro bentou and another tank on B18, I still find B18 has a more pronounced effect on fertility.

Whether it is potentially the Lactic Acid Bacteria strain used, the highly absorbable form of calcium used, the digestability of the yeast protein or a combination of all above, it appears to work.

Dosage: Once a week, small amount.



- very little is used, so it lasts a long time as it is very concentrated.

- the shrimp are attracted to the food supplement when put in the tank.

- it completely breaks apart into a fine particle mush so that all shrimp can have a bite of the small portion dosed

- it indeed does increase berried rate



- not available for purchase in Australia yet. Available in Japan, Singapore, Hong Kong.

- possible water contamination potential if too much is dosed in nano tank.

Are you able to quantify how many extra shrimp became berried on the B18 compared to the high protein diet?

I bought some last year to test it. Didnt notice a huge difference to be honest while using it. I definetly wouldnt buy it again considering how much it cost and how little you get !!!!

I am not sure what factors might be at play here given that some people get results and some don't. I think the reason why I get a good berried rate with B18 is because I mostly fed highly vegetable based products until recently- hence the B18 being very concentrated and high in protein might have been the trigger.

@anthonyd: what type of main diet do you feed? Is it one already consisting of a fair amount of protein perhaps?

In terms of quantifying @fishmosy : this is quite difficult, but I will use my main TB tank as an example. When I do not dose B18, I hardly have any berried females apart from the one loner every now and then. After feeding B18- within 1-3 days, I have at least one berried female, sometimes 2 at the same time. My TB's are hardly prolific breeders in a 240 litre tank, so I use the B18 to chug my population along as I have a lot of space to be filled ? Because it happens so quickly after the B18, I suspect the ingredients might force a molt, much like chitosan. But it is just not possible to be sure unless someone from Lowkeys actually offers some input here...

Fair enough. I also tend to feed mainly vegetable matter and a protein boost for a day or two generally gets the ladies berried

Looks very similar to the kale tablets I got from Dean a few years back, I've still got a supply and my shrimp do go crazy for it.

I feed mainly different foods from Cologne Shrimp Food and a lot of leaves.

Shrimp definitely loved this product but it is too expensive when you have a very high number of shrimps to feed.

I did recently the translation of lowkeys and other japanese brand products for their european agent.

The ingredients for the B18 were japanese viper powder ( 88%) and dextrin ( 12%).

Hi @anthonyd the ingredients in my original post were consistent information from direct sellers of the product. It does not mention the viper powder at all.

Ingredients: Lactic acid bacteria, crustaceans calcium, reduced maltose, mulberry powder, yeast

Phew, glad the ingredients were clarified.

The closest I could google on Viper Powder is something about a red viper (snake) powder.



I use the B18 power protein as well, and have been for 2 years.

I cannot scientifically prove it, but everytime I feed the shrimp after a long gap (basically when I remember), the shrimp have berried up after a couple of days. It works. 

And I like it cause it breaks into a fine powder after a few minutes in the water, which gives shrimplets another source of food. 

So shrimplets gets a good source of protein for good growth rates.

If you are having issues with shrimplet survival rates, this is one food product you can try.

Glad you get good results too @jayc. If we can't buy B18 in Australia  or mythical Viper powder, we might be able to cash in on Aussie Taipan powder ??

Every animal you have in australia seems to be lethal for human so i m guessing not the best for shrimp.

We dont have any snakes in Ireland, only one type of frog and one newt and the only sharks i saw while surfing or spearfishing were basking sharks, big but without teeth

      Hi new shrimp owner here. I’ve read and done lot of research. I’ve had them for only a short time before the 3 females I have became berried all at once. One is an orange and she has a full batch of yellow eggs. I have a clear, with red saddle and tail and a little yellow. She has a small 4 eggs batch (assuming because she’s new to the tank or a new mom) and then this beauty (as seen pictured. When I read about egg color they are yellow or green. Can someone tell me about these blue eggs? The male is all black.

      Okay, so the title pretty much says it all... One of my berried tts just moulted, and she left the eggs in the moult. What happened, and why? 
      I'm going to try to save the eggs with some sort of extraction, and I'll be very careful. She was pretty far along. I think I'll use the net over bubbler method. Does anyone have experience with this, and particularly the extraction? I won't do anything until I have some idea to go off. 
      Thanks in advance.
      Oh and the moult is under like 2 hours old. Wasn't there when I started watching a movie, was there when I checked back after.
      Going off this video: 
      Hoping the process will be similar.

      So I was sticky beaking in my native tank and spied most if not all my girls are berried , so here's hoping that shortly not only will I have the notopala babies growing up nicely but also a few generations of various native shrimp.
      Blackmore I think

      Easy to identify Chameleon

      Also easy to ID Darwin Rednose

      and another

      And this really full girl that is either a DAS or a local creek shrimp that might in all honesty could be anything

      Welcome fellow UK shrimp keeper! I would think it would be better to remove the shrimp into the quarantine tank and keep them there whilst you treat the fish in the main tank and once you finish treating the tank and fish do a complete water change (maybe 2 a week apart for safety) before returning the shrimps. That would seem the best option though obviously the shrimp would need to be in the separate tank for weeks. I'm not aware of any medications available for ICH that won't kill shriimp and/or snails. With neocaridina they probably will just about survive 30 degrees but you are pushing it close to the limit! I don't believe ich affects shrimps.

      Re-posting here from The Shrimp Spot forum as I need help. Help, 40 litre tank has a ich (ichthyophtyirius multifiliis) / white spot outbreak. We've been able to separate the few surviving neon tetra into an emergency quarantine tank, with appropriate medicine for the fish. We had done this as we had noticed the issue practically too late as we miss identified the white spots as cotton mouth (which the tetra also have). We luckily quarantined the fish from the tank as  the ich reached its second stage as most have matured and abandoned the fish. This has become an issue as even if the neon tetra do not survive the treatment, I cannot re-add them to the tank and I don't want to keep the tank's environment full of parasites. Thankfully ich seem to not be able to effect the shrimp but the medicine we have for them is toxic to the shrimp and the plants in the tank, hence the separating of the neon tetra. I was wondering if there was anything I can do to the tank while the shrimp are still in the tank, as removing them isn't a viable option. We've been trying to get the temp of the tank to 30C and leaving it at that temp for an hour, however the tank's heater is verry slow and doesn't seem to be going up past 27C. From what I've searched 30C should kill of the ich without irritating the bloody mary shrimp too much (too many websites vary their recommended temp, so I wouldn't keep it above 28C long if we were able to get it that high) If anyone knows if there are any ich treatments or methods of killing ich that are safe for invertebrates and potentially plants I would love if they could suggest one.

      For beginners and smaller tanks, I recommend glass aquariums because of their affordability and scratch resistance. For larger, more advanced aquariums, we recommend acrylic because it's lighter and easier to repair than glass.

      Hooray! I was hoping it was molt but he hasnt progressed at all in about a week. Thank you guys so much for your help again. Ill keep an eye out. 
    • jayc
      It looks like the shrimp is about to moult.  I don't keep Ghost shrimp, so I'm not too familiar with how they look when going into a moult. But the white band along each joint is common in other shrimp when they start to moult.
