I think you over feed your fish!

  • We are currently upgrading MFK. thanks! -neo
Depends on the type of fish you are feeding. I realize this being a MFK, big fish site....minimum feeding is required. Yet move into killifish, livebearers, very small tetra's and rasbora's and you will soon have wasted, dead fish. Same for fry. Heck even young discus need to be fed at least twice a day or they will never grow to potential. Not to mention that the smaller the fish, the more livefood required.

I started keeping cichlids and followed you advice about skipping days and minimum feeding. Then when I started keeping other more difficult fish, that advice was bad news. Heck even tropheus need to be fed at least once a day to get good growth.

Yes, its situational. But I still recommend a light feeding hand over all.

Big fish, i'm talking big fish. If I could edit my first post I would.
 
I am definitely guilty of overfeeding. Sometimes I just cant get enough of watching my fish eat. I do vary it up though, and water change as needed... my fish are all very fat.:D

Fatty livers too..

Correct, which is why feeding fish is part art, and part science. Generally smaller, younger, more active fish have higher metabolic rates which requires their nutrient intake to be greater, and more frequent, than many larger species. (on a percentage basis)





Lots of wild fish spend the entire day eating and burning calories without stopping. Healthy aquatic ecosystems are bristling with life. I took part in a bio diversity study that surveyed a few local bodies of water last semester. The healthier ecosystems were teeming with inverts, small fish, salamanders, tadpoles, frogs, ect. For a tertiary consumer, the water is the place to be. Its a never-ending buffet/triathlon combo.



While that may be true of your local North American waterways, it doesn't always play out that way with tropical warm water species, such as those ornamental species of fish that most keep in their aquarium, where in the wild the feed conditions are often dictated by seasonal fluctuations in the weather due to the rainy season (feast) vs the dry season. (famine) And even during times when feed conditions are optimum, while many fish will either be feeding, or breeding, most of the foodstuffs taken in are mostly made up from water, and/or are much lower in overall nutrient density, vs the dry food that most people feed in this hobby. Calorie wise, it is much easier to overfeed a fish in captivity with nutrient rich dry food, than it is feeding a diet that largely consists of water, as satiation levels will be reached much quicker when consuming the latter.



Having said all that, overall it is my opinion that most hobbyists do in fact overfeed their fish, and on this site alone there is ample evidence of that. (obese fish) Most pet owners do in fact kill their pets with kindness, including dogs, cats, etc.


Calabash, N.C., March 12, 2013 – U.S. pet obesity rates continued to increase in 2012 with the number of overweight cats reaching an all-time high. The sixth annual National Pet Obesity Awareness Day Survey conducted by the Association for Pet Obesity Prevention (APOP) found 52.5 percent of dogs and 58.3 percent of cats to be overweight or obese by their veterinarian. That equals approximately 80 million U.S. dogs and cats at increased risk for weight-related disorders such as diabetes, osteoarthritis, hypertension and many cancers.

52.5% of US Dogs Overweight or Obese or approximately 36.7 million

58.3% of US Cats Overweight or Obese or approximately 43.2 million

“Pet obesity remains the leading health threat to our nation’s pets.” states APOP’s founder and lead veterinarian for the survey Dr. Ernie Ward. “We continue to see an escalation in the number of overweight cats and an explosion in the number of type 2 diabetes cases.”

New York-based veterinary endocrinologist and APOP board member Dr. Mark Peterson agrees. “The soaring rate of feline and canine obesity is taking a terrible toll on our animals’ health. There is a vast population of overweight cats and dogs facing an epidemic of diabetes. The best preventive measure a pet owner can make is to keep their dog or cat at a healthy weight. Diabetes is far easier to prevent than treat, especially when twice daily insulin injections are needed.”

Veterinary nutritionist and internal medicine specialist at the University of Tennessee’s College of Veterinary Medicine Dr. Joe Bartges cautions that many pet owners don’t recognize when their pet is overweight. “In this survey, approximately 45 percent of cat and dog owners assessed their pet as having a normal body weight when the veterinarian assessed the pet to be overweight.” Dr. Ward calls the phenomenon of incorrectly evaluating an overweight pet as normal “the fat gap.” “The disconnect between reality and what a pet parent thinks is obese makes having a conversation with their veterinarian more challenging. Many pet owners are shocked when their veterinarian informs them their pet needs to lose weight. They just don’t see it.”


This really shouldn't come as any surprise, considering the fact that many believe that we now have an epidemic of human (including children) obesity here in North America. Another opinion that I concur with.
 
i have a simple solution to this leave your wife to feed them while you work away lol, that way they get a varied diet and a mix feed routine its work for me for years cause i work away a lot lol

Great points.

By the by, when I catch largemouth bass when fishing (please practice catch and release) most of them seem to be at the point of starvation. I'm not sure that big fish can easily catch enough food to become fat - outside of the odd predator that is highly efficient and has learned to adopt to an easy meal - e.g. largemouth bass feeding on trout in stocked lakes - they will wait at the truck that dumps out the trout, and have an easy meal.

In our aquariums however, especially when eating processed foods, our fish can easily become fat.
 
Unless your life's work is the study of tropical fish in their natural habitat, you have no clue what your fish would be doing all day in the wild, what they would be eating and how much. And even if you did, you would still have to map that to the nutrient and calorie content of the food you buy in the store. None of us have the first clue. I don't think fish scientists do, either. And to make it worse, they only guy I've seen post any serious knowledge about feeding fish on this website (RD) just said it's "part art". Great.

And then couple all that lack of knowledge with the different species, at different ages and sizes, and different levels of aggression during feeding time, and I don't think there's any way for a hobbyist to feed fish optimally in his spare time. Maybe, MAYBE, if you have a single wet pet in a tank and you have studied that fish for years, and you've studied his habitat, and actually been to its habitat in person, maybe...but you still don't know enough about store bought foods to match its wild diet.

Lookit--imagine the number of debates that continue on this website for years on end with no resolution about the most basic points of feeding these fish--varied diet or all NLS, how much or how often to feed species X, just to name a couple. Heck, half the time we're not entirely sure what species of fish we have in our tank. We often have trouble sexing our fish when we DO know the species.

Feeding as much as filtration can handle sounds sensible for a second or two....until you consider that on THIS site, half of us have so overfiltered our tanks with 10X turnover and freshwater drips that we could feed our fish until they explode before we'd see an ammonia or nitrate spike. There are people on here dripping their entire tank volume every week!

Does anybody have some commonsense guidelines for feeding a 6-12 inch Vieja? Parachromis? Amphilophus? Herichthys? Trimac? I've never seen that. "At 8-10 inches, a Vieja/Paratheraps in good health should consume ? 3mm NLS pellets per day. Or, ? 3mm NLS pellets per week, with 2 days of fasting". Now THAT would help me.

Because then, everyday, I could net out each one of 20 fish in my tank, put him in a 40 gallon to feed him the right amount, and then put him back in the main tank.

Look, I love keeping fish, and I love all of you....but, at some point, we have to just admit that we don't know what we're doing. Just throw some pellets in the water and keep the tank clean. Anything more is navel gazing.

A common sense guideline that one can always fall back on is to gauge how much you feed, by the growth and overall physical makeup of ones fish. Feeding too much, fish gets fat & lazy, feeding too little, fish shows poor growth and gets skinny. Too much solid waste being produced, try a different brand and compare overall digestibility. No one can tell me what MY fish needs for optimum growth and overall health, because no one but me knows it's activity level, and overall behaviour, in MY tank. Maybe your fish does great on six 3mm pellets once a day, but mine does better on 5 3mm pellets, twice a day. You have to find your own groove, and what works best for your fish.

No need to have a background in the science of fish nutrition, a little bit of common sense goes a long ways towards the "art" part of the equation. The rest comes with time, and experience.

Very true,

To everyone, my original post, as I am the OP :) states poorly, that as a general rule I'll bet the majority of us overfeed. That's it.

I don't know whats optimum, I just know that me, in my desire to feed my fish, overfeed them.

My point is I have a heavy hand, because I enjoy nurturing, and like my mother and mother-in-law, that means cooking and feeding food to those under your care - as much as you can stuff in their traps.

And I think its better to ever-so-slightly underfeed, than it is to power feed... because ever-so-slightly underfeeding for me is probably exactly what my fish need to thrive.
