How important is dietary consistency?

I would like to start a conversation on whether the golden rule for shrimp keeping : "Shrimp don't like change" applies to diet and feeding as well?

I have received some great advice from Disciple and would like to find out what the consensus and experience is out there with different shrimp varieties.

In the natural habitat, the diet will be quite consistent in terms of micro organisms, leaf litter types, pollens, insects etc and I am beginning to think that I have been approaching my feeding of my colonies incorrectly. I feed my shrimp different foods in rotation everyday to make up for as much potential nutrient deficiencies compared to what they might find in nature as I am concerned that in the long term I might risk giving my shrimp a deficiency of some obscure mineral like Boron as example, so I compensate with ridiculous amounts of variety in foods. I need to stress that I do not overfeed.

I am wondering whether the shrimp might perhaps prefer the predictability of routine? As an example, only happening in my large 240l TB tank, everyday late afternoon, the shrimp start waiting at the food bowl area- approx 80 percent if my shrimp hang around the feed arena from about 5pm...

What are your thoughts and experiences?

I disagree with the premise that a shrimps diet is "consistent" in the wild. Firstly shrimp are opportunists in that they will eat anything they come across. Dead fish, dead insects, leaves, algae, detritus, pollen, fruits, ect. Secondly these foods will vary from season to season, and even over the space of days or weeks. For example, during times of floods/heavy rains, most of the leaves, moss, plants ect. are washed out of the system. I'd suggest the shrimp then rely on algae growth and detritus. Alternatively smaller rainfalls may wash lots of leaves into the system. Pollen and fruit are seasonal. Algae growth is somewhat seasonal too - higher growth in summer with warmer temperatures and longer day length. There are many more examples. 

It's probably likely that most people provide a greater variety of food than is absolutely necessary to provide all the nutrients, vitamins and minerals that are required by shrimp. This is not a bad thing, but it's important not to get hung up on it and ignore other important factors that determine the health of our shrimp - water quality being the obvious example.

I used to feed a very wide range and variety of food both commercial and natural. Once I started feeding leafy greens and mulberry leaves my shrimp consistently left the commercial food which I had to siphon out each morning. 

My tanks are well established - 3 years plus- although they have had new substrate everything else remained the same - filters, mosses plants etc. I think now with the amount of biofilm in the tanks the shrimp show little interest in most foods except the mulberry leaves and shrimp snow - soya bean husks- my colonies are growing in large numbers and there are very few deaths so they must be getting reasonable nutrition from what is available. I have now stopped feeding vast varieties of commercial foods and cut back on  a lot of other natural foods.

i now have 3 staples in the tank all the time - I have an Indian Almond Leaf in each tank that is left there until only veins are visible, I have a mulberry leaf which again is left until only veins are visible - the leaf tends to get quite " mushy" after a few days and this is when the babies love it, and my final staple is a bit of snow which I end up siphoning out weekly and putting a fresh lot in - the shrimp like it best when it first goes in.

I use a commercial food about 3 times a week . I just make sure it is a good brand shrimp specific food - generally I end up having to siphon it out the next day but I always offer it hoping the shrimp will get some benefit from it.

i was feeding bloodworms once a week but I'm finding the shrimp don't seem to be interested in it like they used to so I feed it occasionally but not weekly. 

I used to feed cucumber, broccoli, spinach, lettuce but again the shrimp don't seem overly interested however I grow my own kale for them and offer that occassionly which they will graze on but not as much as the mulberry leaf which is their absolute favourite food.

i use Boss Baby powder mixed with a variety of crushed foods including spirulina for any tank with shrimplets in it - I use this daily.

i also use micronecton powder and BETA-G or Boss Mineral powder weekly after water change. 

I have high shrimplet survival rates now with this regime

Thank you for your replies guys. It is very interesting that all 10 of your tanks prefer the leaves and start shunning the processed food Ineke. I guess nature knows best...as far as variety is concerned, I might set up an experiment in one of my tanks to see what the result is, if there is any.

Same experience as @ineke with my natives and cherries re shunning processed food, but I haven't tried a huge range of processed food yet.

      I have 18 shrimp in a 90l tank. They have never shown much interest in any food I give them. I give them a pinch of spirulina every 3 days and three or four pellets of JBL Novo Prawn.
      I've tried blanched vegetables, hibiscus flowers etc and the ignore them all. Dies this mean they have enough biofilm?
      I have thousands of detritus worms, including some which are swimming about in the water column, which would suggest I am overfeeding, though this seems hard to imagine with the tiny amount I am putting in.  
      A couple of RCS females are berried so I am reluctant to give up the spirulina as I don't want the shrimplets to lack food when they arrive.

      Hi all. I'm a newbie. I'm keeping a 90 litre tank with cherry shrimp and daphnia together. I'm feeding them spirulina and commercial shrimp food.
       Does anyone know what else I should be feeding them? Anyone else have this mix of tankmates?

      Thanks to the guys at Shrimp Love Mulberry i recently received a pack of the new Mulberry based shrimp food.
      The pack contained 4 syringes of mulberry shrimp food and an instruction card for storage and feeding. Nothing to complicated there, just store the syringe you are using in the fridge and the spare ones in the freezer. Great being able to freeze the syringe and all as you know it is not going to go off so you can order enough for 6 months or more and that will save on shipping costs.
      So like with any new aquarium product i headed straight to the shrimp tank to give it a go. My thinking at the time was that the product would be a bit like Repashy but softer so it could be easily syringed. My tank has a good flow in it so it is always a bit hit and miss dropping food from the surface to the feeding bowl, like wafers or crack, but i'm getting pretty good at hitting the mark. I held the syringe at about the right point to get the bowl and gave it a little squeeze. This is not how you do it...Lol 
      The product came out in a nice tube about 2-3mm wide, like a soft bit of crack, and then hit the flow of water. It then turned into a snow of mulberry goodness as it fell through the water column and was evenly distributed throughout the entire tank. This is not a problem for giving the shrimp a general feed, providing you dont over feed, but there was now no way i could see if the shrimp were attracted to it specifically so i could give it a subjective review. The shrimp got excited as they knew there was food somewhere in the tank but i think it took 10sec for every shrimp in the tank to find some of it and settle down for a munch.
      A few days later it went a lot better. 
      Getting the hands wet i put a bit into the feeding bowl and sat back with the camera ready. My display tank has a mix of RCS, Native WA Glassies and a few Pygmy Cories. I have found that the Palamonties Australis are more of a carnivore than RCS and will rather eat live black worms than actual shrimp food. Fortunately, or unfortunately for a review, the much larger glass shrimp got into the food bowl first and the RCS were kept at bay until it had it's fill. I had put in about enough food for a normal 3-4 day feed and it was gone in about 2 hours. My normal harder food last about 6-8 hours for the same amount.
      Future feeds will be done from the surface again as i dont over feed and the distribution in the tank ensures all the shrimp, even the new ones, dont get muscled out.

      Hello, just wanted to show another food source I grow for my shrimp and snails. 
      Algae.
      Just how it looks, a plastic tub filled that gets lots of direct sun, I usually fill it with old water from my planted tanks to help the process.
      Its a bit full ATM lol but there's a second tub underneath for extra strength.

      I just grab a small pinch and put it straight in my shrimp tanks, they all go nuts for it.
      Alternatively you could remove excess water then dehydrate it on baking paper to make a dry feed.

      An hour or 2 later:

      I picked up a packet of Hikari Crab Cuisine at the LFS and then noticed it contains copper sulfate.  I was thinking of feeding some to my neocaridina davidi var. orange until I noticed the copper sulfate in the ingredients.  Plus, I realize now Hikari also makes shrimp cuisine but I believe it also contains copper sulfate.  The only thing the shrimpettes have ever been fed is biofilm and Marineland Color Enhancing Flakes which supposedly does not contain copper according to the company.  Am I taking chances feeding the Hikari Crab Cuisine to them?  Or, is this the type of copper that is actually good for them in small amounts?

      Great shot of Big Mama!  I reckon, 1 week tops for hatching.
    • sdlTBfanUK
      Great photo and news. The eggs are fading yellow but there are eyes so all looking good and there are a lot of eggs! Probably about half way ready to hatch.

      Let's hope the big mama can lay safely those eggs

      Sorry, I'm not in that area. 🙃   I prefer Glass tanks. Acrylic scratches way too easily. Often while cleaning algae off the sides. And once it's built up enough scratches, viewing gets obstructed.    Often going with LARGE tanks, you start to fall into custom built stands. So don't be surprised if you cannot find anything suitable.

      The easiest way wouod be to go to an aquarium shop and get a tank with a cabinet made for that tank, as that should be able to support the weight, as water in any large quantity is very heavy. I suspect it would have to be a glass aquarium at that capacity, otherwise the plastic would have to be very thick. It is possible to use a non aquarium specific piece of furniture but as you say it is quite risky, though I did help a friend do that by strengthening a nice decorative piece of furniture they had that they wanted to put a 350L tank on. It has been doing the job for 10 years but also bear in mind water marks, and we had to varnish many coats to make sure water doesn't soak into the wood etc. Its not really worth it in reality, it cost a lot of money to buy all the wood/stuff to strengthen it so was probably no cheaper, and a lot of time doing it. It may be dearer to get a combo tank and stand but much much easier and safer, and only you can know what ones you llike the appearance of? I would start off going to local stores and seeing if they have any you like, and even if not it will give you ideas?
