    So.. coming from the “Questions on Puntius” thread, and this picture:

    What is the point where fish become overfed? I like to keep my fishes fat, though I can genuinely say I’ve never had such a seemingly obese fish.

    Discuss!

    ive never really had any fat fish- only problem i can see is that they produce more waste, and may become less active as they have less to do (ie not searching for food) as well as the obvious health problems, pleasantly plump fish (by the sound of it what your talking about) are different i think to the one above !!

    Yeah indeed Neill. That fish is literally obese :/ Doesn’t look happy at all.

    the only time a fish should look like that monstrosity is when they are very young fish, to promote the growth rate, like this.

    i’ve seen some very obese cichlids in my time, but these are people that think they are keeping them happy, then along comes me to tell them they’re actually giving their fish a premature death and to cut the feeding by at least a half of what they were giving before.

    I think a lot of folk just chuck food in whenever they´re near the tank, especially if they have guests round or something. I only tend to feed adult fish 5-6 days per week to keep them a bit hungry. There´s no way fish find plentiful food on tap in nature.

    I also give a day a miss per week on my adults, spawning fish & fry get fed 1-2 times daily

    Yeah indeed. I don’t actually have any adult fish

    Hey

    Most greedy fish I have kept were adult Clarias. At times they ate so much at one sitting that they had to be fasted for a couple or more days to return to ‘normal weight’. Lovely fish though with personality.

    Regards David

    I think that’s part of the problem. Fish instinctively eat when they can, which leads to people overfeeding because the food always gets eaten.

    Agree with the benefits of skipping a day or two each week.

    When I worked at the IAC, our marine manager ordered a Remora. This thing was about 20″ long or so, and to date I can’t think of a more stupid marine fish I’ve ever seen stocked by an LFS. This thing would eat, eat and then eat some more. One of the saturday staff fed it a gamma pack (Remember them) of lance fish. It ate it all, so he gave it a second whole pack of mussell.

    Unbeknown to the rest of us, he carried on feeding the fish. In total it went through 5 whole packs. It’s stomach had swolen like a ballon, to the point where the fish sunk to the bottom of the tank, and could no longer swim! Despite it’s best attempts.

    We were all certain it was going to die. The lad responsible was told, that if it did,he’s be sacked and was banned from feeding the fish ever again.

    Miraculously, the fish survived. But it sticks in my mind as I’ve never seen such a piscatorial glutton!!!

    I like my fish well fed but I don’t over do it. I’m also happy to skip a day per week, sometimes even 2 if they had a good stuffing of frozen foods.
    I admit, I have “overfed” a fish once and I was very frightened as it’s my fav fish, BR, 12″ BGK. I gave him too many prawns and for 3 days he wouldn’t come out and eat. Then on the 4th day I noticed him jerking back n forth (no dirty comments!!) and then he regurgitated the prawns /sad.gif” style=”vertical-align:middle” emoid=”:(” border=”0″ alt=”sad.gif” />
    What frustrates me is this, on a LARGE Monster forum I keep seeing people saying, “my bgk has grown from 3″ to 10-12″ in 8months/1 year”
    These fish have a life expectancy of roughly 25-30 years and a size of roughly 18″-20″ in an aquarium given the right conditions. Growth rate of 3″ to 10″/12″ in about 1 year doesn’t seem right to me /smile.gif” style=”vertical-align:middle” emoid=”:)” border=”0″ alt=”smile.gif” />

    I’ll confess I have used a commercial, shall we say “food fish feed” to feed my cichlids and catfish. It’s high protein and enriched with vitamins and minerals and therefore does help fish grow on rather rapidly…

    When conditioning fish I have a habit of feeding the adults 3 or 4 times a day. I use a combination of live food (grindal worms, white worms and chopped earthworm) and frozen food. Too many types to list.

    My existing fry are also fed 3 or 4 times a day. So I guess this is overfeeding. However, my filtration and water change routine are taken into account with such heavy feeding.

    My female Corydoras sterbai look ready to explode right now. They’ll have a couple more days stuffing themselves, and then I’ll switch the heater off overnight and do a cool waterchange. After they have spawned (I’m 90% sure they will) I’ll go back to feeding them once, maybe twice per day.

    so…seeing that I’m supposed to jump in…overfedding obviously stresses the kidney and liver, wear and tear of the organs will most probably make life span shorter. Also one must remember that the high lipid levels (fat) would clog veins, and other passages in the body, thus causing complications.
