I've heard before that feeding your fish freshwater shrimp is better because the fish already has to rid of so much excess salt in the water so by feeding it a non salty food its less work/stress on them. (something like that, not sure if i got it right)

+1 on the PE mysis. This is the only other food that my copperband butterfly eats. Come to think of it, that fish mostly eat only non-saltwater diet for 9 months now...live white worms and PE mysis, with occasional mussel.

If it was so bad, he would not be as fat and healthy as he is right now.

It's not so great when your fish refuse to eat it because they prefer PE mysis, Just sayin :wink: Although it could be because my fish are so used to the PE mysis and I buy the larger packs so the PE mysis shrimp are larger then the Ocean fresh shrimp.

+1

where did you hear that from?.....fresh water mysis promotional material:razz:.....I dont know, but if that were true, all saltwater fish would congregate at the mouths of rivers and tributaries to eat fresh water food......cmon.....saltwater fish have evolved over millions of years......do you really think that they cant deal with salt?.....seems like kinda, a baseless piece of trivia........kinda like "fish can die from micro-bubbles"



sounds like I did ruffle some feathers:biggrin:........for the record I never said that PE mysis was bad...... I merely stated that there was a better option.......


well then your fish in each of your own little worlds must be representative of all fish:razz:.....kudos to you Daniella for trying the best you can to most accurately replicate what the animals you enclose in a glass box eat:mrgreen:....all I know is we have fed literally hundreds of fish at the shop with "ocean fresh" plankton and had great results.......probably somewhere in the neighborhood of 80% of the people that shop at RCC use ocean fresh and swear by it..........you two should maybe open your eyes and give something new a chance.......you know......kinda like "Ive been feeding my dog purina dog chow for 5 years and now he wont eat this other brand that should be better for him".......do you still continue to feed the dog chow?.....

I don't have a favorite but here are my top choices. I feed different food for different fishes needs.
Cyclopeeze for smaller fish(Nano), mandarins, coral, gorgs. I've never had a problem to get mandarins to take cyclopeeze as a first food. They are pod eaters so they get pods(cylopeeze)
PE Mysis has always been good but I like the ocean fresh plankton better. Similar in size but the strong shelfish smell of the plankton says it all for me. The feeding response of my corals was insane with the ocean fresh. As soon as it hit the water everything new it was feeding time. Too bad I can't find it here locally which is kind of funny because it's caught just north of here.
Hikari Mysis because they are way smaller then the PE mysis and a little bigger then brine shrimp. Sometime PE mysis are just too big.
Being right on the ocean, some of the best I feed would be stuff I get locally and freeze myself.(Uni-Urchin eggs, oyster ovary/eggs, herring roe)

I do think there is a difference, but I don't think it is significant enough to be concerned about. For the most part, the shrimp would have little nutritional differences even in a lab. The fatty acid profile would differ a bit, but it also differs from mackerel to sole. A shark and a trout are a bit different from each other, but a freshwater shrimp and a saltwater shrimp...not so much. Honestly, I don't think it makes that much difference. Especially when there are members of the same genus within both freshwater and saltwater eco-systems. If it made a big difference you wouldn't see so many breeders using mysis.

You don't ruffle my feathers. You do bring up a good point, albeit it's arguing Porsche over Mercedes...there isn't a bad choice! :p

probably because there hasnt been an economical alternative(or the market to support it) until recently.......much easier and more economical to harvest shrimp from a freshwater lake in BF nowhere Canada than it is to collect and harvest it from the ocean:wink:

If you want to get into details, most breeders use homemade diets, but PE mysis is often a part of it. Lots of clownfish breeders just use pellets/flake.

People have been collecting and using/selling all sorts of saltwater plankton for like ever Doug. :lol: Hikari or HBH or Sanfran Plankton and mysis are all same price.

How much fatty acids are more than they get in the wild? Why would you want to feed your salty friends more?

Supporting analytical data illustrates that PE Mysis has less Crude Fat (8.35% dry weight) compared to that of the Ocean Fresh (18% dry weight). The PE Mysis also has a higher Protein content (69.5% dry weight) compared to that of the Ocean Fresh (58% dry weight). High Ash content is one parameter that I have always watched. It appears that the PE Mysis is much less (5.5% dry weight) compared to that of your Ocean Fresh (13% dry weight). I cannot compare the heavy metal contents analysis, but do see that they exist within your Ocean Fresh.

I understand that the Aqua Treasures and the PE Mysis Shrimp are harvested from the same freshwater lake, however, I cannot find any comparable analytical data on them. I find them less Oily than the PE Mysis.

so I guess tens of thousands of years of evolution and feeding on food originating from where the fish actually lives have produced obese, unfit and unhealthy fish?....fact is........saltwater fish live, grow, thrive because of their environment and what they eat out there in the wild......we bring them into our little boxes and feed them "suitable substitutes" (in our eyes), get five years out of them and think ......."well he lived five years.....thats pretty dang good"......when, if left in the wild eating OCEAN FRESH plankton (a fatty, low protein, high ash food) they probably would have lived 10, 15, 20 years......now I dont seriously believe that diet is the only factor shortening a captive fishes lifespan, but.........
