180 degree switch in fish food: lost too many show fish, need better food

  • We are currently upgrading MFK. thanks! -neo
Freshwater fish are relatively easy to keep healthy, long term, especially cichlids. I posted the following recently in another discussion.

A fish that eats detritus in the wild does not do so because it is the best nutritional option available in their ecosystem, it does so because it has evolved over many years to survive on the waste of others. That has become it's niche, and it is about survival, not because it creates a nutritional advantage for the fish.

I have yet to find a species of cichlid, that cannot be kept healthy & thriving for many years, on a diet of pellets. Often, far more years than the average lifespan of the same species in the wild. A well maintained glass box is easy street compared to the feast & famine cycle of nature.

Viktor's carpintis didn't die from eating the wrong food, it died from eating too much food. It was grossly obese! Had a necropsy been performed the fish examined would have with almost certainly showed fatty infiltration of the liver, heavy vacuolation, and severe necrosis of the liver, pancreas, and spleen. That's what killed his fish, not because leaves and detritus didn't make up part of his diet.

Cichlids are a snap to keep in captivity. If you want a challenge set up a marine tank. Then stock it with some of the more sensitive marine species, such as Rock Beauty, Moorish Idol or Achilles Tang. For species such as these a mediocre diet results in a very swift death sentence for the fish. (weeks/months, not years!) It doesn't matter how much variety you offer them, if the nutrients aren't provided in sufficient quantity, in the proper balance, and in a form that the fish can fully assimilate, the fish simply won't survive. It's that simple. Yet even those species can now be successfully kept thriving in captivity, for years.


The OP has a feed situation far different from the average aquarist, or MFK member. His "tanks" are massive, and numerous, with hundreds of large hungry mouths to feed. The cost is just as massive as his tanks, he needs a solution that will be nutritionally suitable for his fish, while at the same time not breaking the bank.

As I previously alluded to, some of the fish in certain tanks may need to be moved around, so that feeding behavior (aggressive feeding species with aggressive species) also matches their feeding type (carnivore/omnivore/herbivore) while overall feeding a lot less. There are some doable workarounds that Viktor can apply, I think that we should all focus on that. I think that Viktor's switch to a much higher nutritionally quality food is a step in the right direction, I was simply attempting to help him save some of his hard earned $$$ while doing so.
 
Ok, I see. Most mills won't be interested in making up small batches of food, some might, not sure? I suspect most would want a min of 1,000 pounds to make it worth their while, some possibly a 1 ton minimum. Ken does the same as the eBay vendor, I don't see him being a cost effective manner in which for you to feed your fish. You need to totally remove the middleman if possible. Then find a decent food, that a producer would be willing to sell directly to you.

I have the space to store 100 ton but it will not be as cool, dark, and dry as would be the best, is what I wanted to say. To spend 1000 lbs will take me probably very roughly 20 months. I am afraid the food will not have been fresh after several months.

So Ken of Ken's fish food is not a miller but a middleman too.

I have had a relationship with Zeiger for over 10 years, so I can ask them. As for other millers, IDK who they are, their names, etc. I am clueless. How do I look this up? Is there a list of the US based ones?

One of the problems I perceive in how aquarists feed fish (not necessarily the OP, but in general) is they don't recognize that there are different trophic types...

Thank you for that.

P-bass are highly piscavorus, so require high protein, but is all protein created equal?
Can a P-bass actually make use of grain protein, or chicken parts to a healthy advantage? Maybe, maybe not.

Right, which is why I am looking for better pellets based on aquatic animal protein sources.

Herichthys (like carpintus) and a number of Central, South American, and other cichlids in general, are omnivores, with a tendency toward getting at least 50% of their diet from algae, and a large% from detritus.
So does vegetable protein from legumes, or protein from chicken parts actually fit in to those intangible ingredients?

Agree again, which is why I am looking for pellets based on the ingredients of aquatic origin, not terrestrial plant or animal.

I have watched bocourti and pearsei eat waterlogged wood in much the same manner Plecos do, and have watched bocourti reduce papyrus plants (essentially paper) to nubs. Are papyrus and water logged wood nutrient rich? I doubt it , but do they have some intrinsic value beyond just nutrients to the digestive traits operation? The digestive tracts of these species are often twice the length of other similar sized fish and I highly doubt they would eat it if were not of value.

If you are saying you observed it in the wild, it may be rationalized as they were hungry and willing to fill their stomachs with anything even remotely edible. Or they needed 100% fiber to sweep their intestine clean for one reason or another. I also read that cichlids (all or not IDK, those were studies of African cichlids) are able to adjust the length of their intestines to the currently available food source, which is mighty remarkable.

Lastly, much of the aquaculture foods are made to provide accelerated growth, in a short time, so those fish can end up in the grocery store shelf quickly. Is this accelerated growth good for a healthy long lived "show" fish? Maybe not. Is it a good idea for us to accelerate the growth of our fish ibeyond the norm because we want them big fast, in the long run? Maybe not.

Agreed too, which is why, again, I am looking for better pellets. Thank you for expanding on my reasons of wanting a better food for my fish and for the info on the variability of needs in cichlid nutrition. Much appreciated.

I’m a subscriber to your channel Viktor! :). Have u considered milling your own pellets with an extruder machine? Additional content(s) for your series. :).

Thank you so much. Is it easy once one gets the machine? Are the machines affordable? I've never even looked into it. I'll make it a point to.

Thank you for these clarifying paragraphs.

That's what killed his fish, not because leaves and detritus didn't make up part of his diet.

This rings very true from the practical point of view. I am guessing Duanes had the most natural / ideal scenario on his mind, which is a good reference point to be aware of and understand it too, as RD is helping us.

The OP has a feed situation far different from the average aquarist, or MFK member. His "tanks" are massive, and numerous, with hundreds of large hungry mouths to feed. The cost is just as massive as his tanks, he needs a solution that will be nutritionally suitable for his fish, while at the same time not breaking the bank.

To repeat myself for clarity's sake, pellets are presently around $400 a month since I am doing 100% NLS. The other 50% of the food is the frozen whole marine bait fish and VitaChem, which are extra to this, probably another $100 a month. So $500 / month all in all or $6000 / year.

We are growing though...

As I previously alluded to, some of the fish in certain tanks may need to be moved around, so that feeding behavior (aggressive feeding species with aggressive species) also matches their feeding type (carnivore/omnivore/herbivore) while overall feeding a lot less.

I will think and consider the reshuffle. My first reaction is this will be hard or even impractical from other compatibility issues that must be satisfied but it is worth a good thought. So far in my hobby life, I have never bothered to consider anything else but physical safety of tank mates in choosing who to place with whom. Even this is often a gamble and not uncommonly it doesn't pan out.

There are some doable workarounds that Viktor can apply, I think that we should all focus on that. I think that Viktor's switch to a much higher nutritionally quality food is a step in the right direction, I was simply attempting to help him save some of his hard earned $$$ while doing so.

We couldn't appreciate it more.

My bocourti and pearsei ate wood, and papyrus in my tanks, actually visually reducing the size of some logs, and reducing papyrus plants from 4 ft to nubs, so they were not at all doing it out hunger, they were very well fed.
Like pleco's that eat wood, there may be natural enzymes, and bacteria in wood that aid in their digestion, and may be only available in wood products.


Consider tropical parrots that eat clay off dried river banks, it neutralizes certain toxins naturally found in the seeds they constantly eat.

There are also toxins and seemingly indigestible ingredients in certain terrestrial leaves that normally fish eat (many people consider pothos to be toxic) my bocourti and pearsei, also ate it, and other last leaves. Could it be the wood, that changes those undigestables, to needed digestibles ?
I don't consider feeding fish to be, just about the obvious human value judgement knowledge and awareness of nutrients.

As a chemist/microbiologist, I have found the more I know, and learned, the more the mysteries that I didn't know, or learned piled up.

The guy that runs NLS is a friend of mine, he isn't going to make food for Viktor, or anyone else. Neither would the vast majority of manufacturers.

Viktor - IMO you should stop looking at various online vendors, and talk to the folks at Zeigler. If you can't store food in AC cooled conditions, then yes, you will need to keep your feed for a few months at a time, or nutrient levels will suffer.

Yes, Sir, yes.

You speak, I listen and do. Feel free to tell me if I should have written something differently. Here is my first email to Zeigler sent 5 min ago (I called and found through the menu their nutrition specialist but they don't answer nor take voicemail...).

So I wrote to quality control manager I have dealt several times before.

Hi Christopher,

I've been buying Zeigler pellets, specifically aquaculture finfish silver 40-10, for 12 years and now I need to change what I feed my fish. I've looked at all the pelleted food on your website but you withhold the ingredient lists, so I couldn't understand which product could be adequate to my new goals.

I am not a fish farmer, I run an educational Public Aquarium and a Fish Rescue and with years found that fish don't last as they should on the abovementioned Zeigler pellet I feed them. The fish's lifespan is shortened by 2x to 10x versus expected and normal.

These roughly $1/lb delivered pellets do their job well raising fish quickly and efficiently but this is not my goal. My goal is to have the fish live a full lifespan and longer. For now I have switched to the New Life Spectrum pellets, which run me roughly $10-$12/lb. Their ingredient list and quality are ideal and the best there is in my opinion available out there (no terrestrial or non-aquatic major ingredient except the wheal flour binder), but this is the other extreme and I'd like to ask your help in finding a compromise between the quality and the price.

Or perhaps you mill NLS or Hikari or NorFin etc. high quality pellets under their label too and I could just buy directly from you and not having to pay the overhead to middlemen on Amazon and EBay and such.

I also need a better quality feed for our exotic carp and koi exhibit than the finfish silver 40-10. Toward this purpose, a moderate inclusion of ingredients of terrestrial plant matter may be permissible.

I'll await your advices.

If you are not the right person to address, please, forward my email to the right person.

Thank you.
Viktor

He probably means if I could buy directly from Pablo, or so I imagine... Existing products, not anything special for me.

The NLS plastic buckets are hermetic enough, no smell, that I could store at home under AC but we run our AC high, usually 83 F.

Well I don't think that I would have worded it quite like that, but let's see what he comes back with. The only food that I know of that Zeigler private labels, or at least used to, is Xtreme. New Life has their own extruders, and makes their own food on location in Homestead FL. Northfin is produced here in Canada, and Hikari is made in Japan.

83F? That's not AC, that's a tropical heat wave where I live! lol My AC is set at 72F in the summer, now that's one cool breeze.
