Hi everyone, I am a biologist who is breeding glass shrimps, riffle shrimps (one of my favourites), red claw, micro algae, zooplankton and a local endangered fish species (honey blue eye rainbows). I am doing private research into using algae/zooplankton as a sustainable food source for aquaculture and a food source for developing countries. 

My main focus right now is to breed riffle shrimps in large numbers as they are filter feeders and work well with my plankton systems. I look forward to contributing and learning from you all.

Welcome @Riffly,

your project there sounds very interesting. Where are you from?

It will be interesting to know how you cultivate zooplankton, as a number of shrimp species depend on that during their larvae phase (ie right after coming out of the egg).

Would you mind sharing your experiences with obtaining enough plankton to raise shrimplets that depend on it? Amano shrimp and a couple of Australian natives (Darwin Algae shrimp) that could be bred in captivity if people have a reliable source of food for those early weeks in the shrimp's life.


I have tried using chlorella : spirulina 50:50 mix to create a diy green water, but that has mixed results. Plankton + the green water would be more successful.

Hi Jayc, I am from Sunshine Coast, and am happy to share my experience with algae. I am working on a concept which I call algae aquaponics. Algae drives nutrient and energy cycles for my aquaponics. 

I have a 1000l ibc  which I harvest algae daily, which feeds:  3 by 200l drums (2 honey blue eyes fry, one riffle shrimps) , a 1000l ibc breeder tank for honey blue eyes, 300l glass shrimp container, ibc for red claws, and aquaponics.

Riffles are amazing I throw in 10l of concentrated algae mix daily and it goes clear within 1hr. Glass shrimp breed like crazy with constant algae. 

Growing algae is easy, the hard bit is managing boom and bust cycles. Algae is so productive it kills itself with its own success. Below is a summary of how I manage algae: 

1) constantly harvest the algae to thin it out;

2) feed it to your shrimp; then collect solids. I have a bioreactor in with shrimps to convert ammonia to nitrates. 

3) mineralise  the solid waste from the shrimp, converting it to cation/ anion nutrient. 

3) return  the mineralised nutrients (cations/anions/nitrates)  back to the algae.

4) algae/zooplankton goes crazy. Rinse and repeat above process. 

It’s a circular economy that keeps on giving. 

Im in the process of developing a training course (and eventually a web site) on how to build the systems which I can let people know when finished.

@Riffly that would be great! 

Feel free to create a new article or post and I will make sure it is highly visible to all.

      I've attached a small bit to the rock as the tank is currently cycling that had the crystal reds in it . I've always been torn between blue bolts and shadow pandas but blue bolts always wins. I never thought about taking some from my other tank and using them a tester but that is a good plan, saves me getting some blue bolts and then all of a sudden i have a big issue again. Hopefully not . That's why i am glad i have the bigger tank and also any of the lighter blue bolts can go into the bigger tank for culling. I've attached a few more favourite. My favourite shrimp which i think this is correct is an extreme bkk . I've also got a photo of one of my many red wines.  https://ibb.co/BVhDMMK https://ibb.co/42Q3ZYc https://ibb.co/gTD403T

      It may be worth holding off on the subwassertang as when you set up the new tank you can then use it in there? I think I could see a few red wine, if they aren't full size, could just have been the light though! There are 3 half size white shrimp with a red head between the large crs in the third photo of the sponge (about half way down), they are beautiful also .They may just be crs but the photo looks redder than those, but may again just be the light! My overall favourites are blue bolts also. I would use some of the crs though for about 3 months as a tester before getting blue bolts for the re-setup tank, you can then remove the crs. You have lots of the crs and you know they are healthy so it makes sense to use them (free) to 'test' that all is ok first, before getting the blue bolts! It will help mentally also, just think how devastated you would be if for some reason the blue bolts died because there is a problem (you won't know with them whether it was the shrimp or the setup), whereas you would still be upset with the crs dying but not as much - they were free and you have plenty of others in the other tank. If you want blue bolts only in the tank you may well get offspring of other colour/pattern depending on the genes of the parents, but then they can be moved to the other tank. ie Blue bolt mother and blue bolt father may create something not blue bolt, depending on the genes etc.

      Thank you, i enjoy a simple scape although i really need to try and take both sections of subwassertang out for a trim. They have just gone mad.  Things are doing great in this tank, i love my red wines as well bit couldn't find any at the time of taking a photo.  There is but i'm not sure they would breed true, i suppose it could be a project for me to breed them true but wouldn't know where to start. My other project i was thinking is just blue bolts in that tank , i love the colour.  I also suffer from slow breeding in winter although i've never had so much success with my taiwans/mischling that i hope it continues.

      That is a fabulous tank, is it built into a wall or partition. Love the simplicity of the layout, you can see lots of shrimp - I tend to overcrowd mine with plants so don't get to see so many shrimp. Great to hear that this tank is doing well and you have quite a few shrimp in there! Especially like the panda and blue bolt in the photos. As you have so many crs in this tank you shouldn't need to buy any more for your reset tank so that will be great and you know the shrimp are good quality and healthy, and that will make a bit of room in this tank for the next generation at the same time? You may experience the slowing down or stopping breeding for winter, though not everyone has that? Thanks for the photos!
